Building the Kit

The Lightning kit is considered a quick build kit in industry terms with the highest completion rate of any similar performance experimental aircraft kit. Some other kits are taking their builders in excess of yen years to build. Yes, the Lightning is truly a quick build kit that meets the 51% rule for Experimental Amateur Built (EAB) aircraft. It should take an average builder with some mechanical skills about 800 hours to complete the basic structure of the Lightning. A two car garage is best, however it has been done successfully in a single car garage. A comprehensive build manual, with good photos and simple CAD drawings, is on-line to help you through the process. The manual is online in the support section of the website. There is also a Lightning chat group which you can join and get ample amounts of building tips and suggestions. You can always call us here at Arion Aircraft, LLC, or any of our dealers to get the help you need in building the Lightning kit.

Optional Items

For both the XS and Classic “Go-fast” kits, we offer a speed fairing kit. This will increase cruise speed about 10knts, and decrease fuel burn. They are tedious parts to fit and install, but well worth your efforts in performance and looks. If you decide to build your kit to meet the LSA requirements, you will need to slow the stall speed down. We offer a wing tip extension with winglet to do so. This will add roughly 12sqft of wing area, and bring the span up to 30’ 6” from 27’ 2”. Even if you are not building an LSA compliant kit with a Jabiru 3300, this will help climb rates, takeoff distance, and, if installed on a “Go-fast” Lightning, increase the cruise speed about 8knts above 10,000ft.  Other items which are optional include: landing light pockets for the wings, boarding steps, aluminum spinner, and a few others.

What's Not Included

You will have to get an engine. A prop that is suited to the plane you are building must be purchased. We have tested a lot of props, and we can suggest a prop for the Lightning you are building. The kit does not come with any avionics. Since this is one area that many builders like to add their own touches to, we do not supply any. Also with that in mind, we do not supply an interior. There is a local shop here in Shelbyville that does our interiors, and we can supply a custom kit to meet your needs. There is no paint, but you will have a gel-coat surface, free of pinholes to start body prep on. Because you are building a fiberglass aircraft and will need extra epoxy and resin from time to time, or fiberglass cloth, we do not supply it. Arion Aircraft, LLC does not have the correct chemicals approval to ship these items, so the cost is eliminated from the kit, and you will need to purchase your own from Aircraft Spruce.

Introduction

The Lightning EAB was designed to be an easy to build and economical to operate kit aircraft. The components used and techniques employed to build the kit do not require any special knowledge, tools, or building space. The kit is very complete and leaves little searching of suppliers for parts. All hardware is AN, the painted pre-welded components are 4130 steel, and all machined aluminum parts are of the T6 grade. Other airframe parts include: aircraft wheels and brakes from Matco, control cables from McFarlane Aviation supply, and a canopy formed by one of the Leading companies in the industry. This is all put together in a kit, along with a comprehensive build manual that will take the guess work out of finding components to complete your Lighting, and get you in the air quicker.

What's In the Box

All main fiberglass assemblies are pre-formed and fabricated. This includes: Fuselage halves bonded together with bulkheads installed, wings closed with fuel tanks installed, all flight controls pre-molded and closed, cowls, spinner, canopy frames, cockpit seats, and baggage floors. Welded structures, such as: motor mount, spar box assembly, gear leg sockets, and various brackets, are epoxy painted and ready to install. The landing gear is machined from 7075T6 aluminum and ready to fit. Other components are machined from 6061T6 and are ready construction. Also supplied in the kit is raw stock 6061T6 aluminum for fabrication of longerons, pedals supports, bell-crank mounts, and other various brackets. Some fiberglass tape is also supplied for different tasks. There are a variety of components that are sourced from other aviation industry manufacturers. The Wheels and Brakes come from Matco Mfg (these are the 5” size and use standard 500-5 tires). The Canopy and quarter windows are supplied by Aircraft Windshields Inc. All hardware is drop shipped from Aircraft Spruce.

The Airplane…

Design and construction, structure/materials, quality control.

The Airplane Factory is proud to be the producer of high quality, high performance Light Sport and Experimental Aircraft. We take every step to ensure that each aircraft produced, whether ready-to-fly or kit version, is held to the highest of standards, above and beyond that required by ASTM or the FAA. The reason for such meticulous design and construction is because most of us here at The Airplane Factory are pilots. We know and understand the concerns of our fellow aviators and we would never build anything we did not 100% believe in or endorse. Every new design prototype is tested to its ultimate breaking points to ensure maximum reliability and durability, not too mention the extraordinary efforts The Airplane Factory goes to in order to make sure handling and stability are in the upper echelon of all airplanes on the market today. In addition, each kit we produce is inspected and assured to be top quality before being shipped to the buyer. The Airplane Factory founders feel that the Sling airplanes and kits are the best on the market and believe that you will soon agree!

The design was conceived in 2006 as a result of Mike Blyth’s desire for a Light Sport Aircraft (LSA) that had better performance and handling characteristics than anything on the market. This vision would be an airplane capable of acting as either an exciting pleasure craft or a forgiving trainer. Mike decided to go with a stressed skin, riveted design for its proven technology, durability, and ease of construction. He also wanted to make an all-metal, low wing airplane that would have excellent visibility, sporty handling, and a sleek and sexy exterior.

The aluminum he chose was 6061 Aluminum Alloy. To be more specific, 6061-T6 Aluminum, a tempered grade that has been heat-treated and aged to add a significant strength element. The Sling uses all traditional AN Hardware in its construction, meaning it lives up to the US Air Force/Navy Standards. Solid rivets are used on the main spars, which are standard aviation type spars with our own unique design for added strength, and pull rivets for the rest of the structure, making construction a bit easier while maintaining structural integrity. The Airplane Factory uses high quality rivets manufactured in Germany that are well known throughout the aircraft manufacturing industry. Composites are also used throughout the airplane where appropriate, for example, cowling, fairings at the wing roots and the intersection between the vertical stabilizer and the fuselage, wheel pants, as well as the instrument panel and canopy structure. For reduced weight but added strength, the landing gear is also composite construction which can take a heavy amount of stress regularly without issues.

The standard assembly process for each Sling begins with the different aircraft subsections being assembled. After the Empennage, Wings, and Fuselage are ready they are sent off to receive their Primer and Epoxy painting. Concurrently, the engine, electronics and canopy are fitted. When the parts come back from painting the wings and empennage are bolted to the fuselage and tested. Lastly, the fairings are put in place and the aircraft is ready for testing.

Each part of the aircraft manufacturing process has a full set of quality control procedures that The Airplane Factory directors personally oversee. Each part part is carefully inspected and all metal is punched precisely by our CNC machines. The quality assurance managers then inspect the entirety of the shipment before sending out to the buyer.

Best Experimental Planes

Joe Haygood

March 7, 2023

This article may contain affiliate links where we earn a commission from qualifying purchases.

‍ Key Takeaways

  • The best experimental plane is ultimately the one that best suits all your overall needs
  • The fastest experimental design is the Lancair IV-P, whose top cruise speed clocks in at almost 350 mph
  • Teh Lancair Evolution is the best experimental for seasoned pilots
  • The Velocity V-Twin is the best experimental
  • The easiest experimental kit aircraft design to build is the Hummel H5, which takes less than 1000 hours to complete start-to-finish

‍ Experimentals come in all shapes and sizes these days. Spoilt for choices, it’s hard to pick the one that will give you the best experience.

The best experimental planes are the perfect aircraft for your needs. They include:

  • Lancair IV-P - fastest top speed and cruise speed
  • Extra 300SC - best for aerobatics
  • Lancair Evolution - best for seasoned pilots
  • Pelegrin Tarragon - best overall
  • Velocity V-Twin - best twin
  • Hummel H5 - easiest to build

With experience in nearly every aspect of aviation imaginable, I have long admired all types of certified and non-certified aircraft, and even worked for a company who used to sell experimentals prior to completing my flight training.

Table of contents

‍ my criteria.

Experimental aircraft are one of those classes of aircraft that’s somewhat misleading. The general public, and indeed many pilots, often assume they are aircraft (particularly military ones) currently under development.

However, at least as far as the FAA registry and flight regulations are concerned, these are not the only types of “experimental” aircraft (these, in fact, are known as demonstrators). Instead, the FAA uses it as an umbrella term for a variety of aircraft types that don’t fit into any of the other aircraft categories laid out by the FAA.

For the purposes of this article, I am only including aircraft that fit into at least one of the following categories:

  • Kit aircraft
  • Ultralights
  • Light sport aircraft

As such, no UAVs, demonstrators or air racers - all of which also fall into the “experimental” category - have been included.

When looking at the “best” of anything, it’s important to take into account the differences in pilots’ needs. After all, some will need speed above all else, whilst others will need something like simplicity, range or any other number of factors.

As a result, each entry on this list covers a different aspect of potential needs. These aircraft are chosen as they are the best in their particular sector based on my years of experience in the aviation industry and with experimentals in particular.

Lancair IV-P - Fastest Top Speed and Cruise Speed

The best experimental plane that you can use for frequent personal transport on long distances is the Lancair IV-P . The 'P' in the model name refers to the fact that this experimental plane is pressurized, making it one of the few pressurized experimental kits available on the market.

But that's not the only reason this plane takes the top prize among all experimental planes to be the best personal transport experimental plane. This plane, even when it is flying at its top cruise speed of almost 350 miles per hour, is, by far, the smoothest plane you will ever fly. And that includes Normal Category General Aviation twins.

Another reason this is one of the best planes ever designed, and not just in the experimental category, is because it is one of the easiest planes I've ever flown.  Whether it's high-speed long-distance runs, or lazy-eights and chaendless, the aircraft handles with crisp yet graceful personality.

The flight characteristics that make it one of the best - like its handling, speed, and agility, sometimes are enough to make you forget that it also shines because it can be all those things while carrying four adults. When you want an aircraft to be your personal transport, you want to be able to take family, associates and friends.

If the plane has just seats for four but load limitations dictate just you and a bag, then there is no point. The Lancair is not that way. Its four seats can take 4 FAA-sized adults and still be able to top off the tanks.

With a fuel capacity of 90 gallons and a twin-turbo engine which burns 20 gph, flying at FL290, the Lancair can leap across 1300 nautical miles and still land with IFR reserves intact. It can do that without needing its passengers to tether themselves to oxygen cannulas because Lancair pressurized the IV-P.

And they did it with an aircraft made almost entirely of composites and similar other components. Its fuel burn of only 20 gph also makes it one of the most fuel efficient aircraft out there.

Whether you’re a passenger in the Lancair, or the Pilot in Command, the comfort you feel from smooth flight is only amplified by the characteristic peace you feel in the relatively spacious cabin. The thicker walls of the composite not only have good sound absorption qualities, making the cabin quieter.

Closer to earth, the Lancair proves itself yet again as it is able to leap off the ground on take off, and come to a halt on landing in fairly short distances. It is not necessarily a bush plane, but its wing area means it can land on turf, does really well coming in and getting out of paved and unpaved runways. Just needing 1500 feet to get out and under 2000 feet to get in, the Lancair can get to just about any airport in the country, or in the back country for that matter where there are lots of short runways.

The IV-P has optional speed brakes . Whenever possible you should get it, just because this plane was not designed to go slow, and so when you do want to slow it down, it will take a lot of effort and preplanning. In most cases, pilots extend the landing gear and deploy the flaps to decelerate, but since that can’t be extended until you’re at 145 kias, your descent profile from FL290 can get tricky.

But that’s about the only thing that you have to watch out for - speed management. Other than that the aircraft is as simple to fly as your first complex trainer.

When it comes to experimental planes, each design is built to do something specific really well - let’s call it its mission. The Lancair’s mission, something it does better than any other experimental aircraft out there, is to travel cross country quickly and comfortably without any fuss.

Extra 330SC - Best Experimental for Aerobatics

One of the sleekest, meanest experimental designs out there that looks as good with military livery as it does with racing stripes is the Extra 330SC - a low wing single engine aircraft tested for up to positive and negative 10Gs.

This single-seat plane has won numerous world titles, including the World Champion Aerobatic Aircraft numerous times. The Extra 330 SC has conventional wings and is one of the most robust builds in the world. It can take high-g maneuvers and perform with crisp agility that is limited by only the pilot’s skill.

The entire aircraft is built using advanced materials in addition to the advanced technology. That results in superior handling, low empty weight, high useful load, and better performance. The Extra SC works well as a sole transport vehicle, meaning you can take this on business trips. It would be the equivalent of arriving in an exotic sports car.

Able to travel at 200 knots, it has an endurance of 3 hours excluding VFR requirements. That lets you get to a meeting 500 nautical miles away. The aircraft is VFR-only, and other than a recreational pilot’s license or a Private Pilot’s license, there is nothing more you need to fly the plane.

It is the best aerobatics plane on the market because of its inherently negative stability profile that allows the aircraft to be manipulated into numerous attitudes of flight with relative ease. The high-wing loading design and relatively large ailerons result in lighting quick roll rates exceeding 400 degrees per second.

The increased roll rates and roll stops allow the aircraft to perform crisp maneuvers with military-like precision.

Aside from its ability to perform advanced aerobatic maneuvers, the reason the Extra 330 SC is the best in my view is that it is just amazingly fun to fly. From its rapid acceleration and short take off rolls, to its extended inverted flight ability, the 330 SC takes experimental flying to a whole new level.

The 330 SC is also one of the few aircraft to repeatedly win world championships and be the world’s number one choice among professional aerobatic champions. It is sold in the United States as an experimental aircraft since it is certified that way by the FAA but in Europe, it is fully certified as an aerobatic aircraft and often takes part in championships in the Unlimited Category.

The 330 SC is one of the best experimental kits also because of its engineering. Not only is the design well balanced and negatively stable, the aircraft is structurally superior to most production aircraft. This is from a structural perspective and from the use of advanced materials, since the aircraft is mostly made of composites, giving it huge structural integrity.

From an engineering perspective, the 330 SC sets the standards for experimental flying, highlighting stability benefits more so than aerodynamic ones that most engineers who are attempting to beat speed records do.

This is the other reason this aircraft, to me, flies so well. It’s more than just the aerodynamics, structure, and propulsion that has been meticulously bought together, it's also about human factors - the ergonomics of flight.

The cockpit, for instance, is snug, and offers a good feel for the aircraft, making the aircraft almost a natural extension of your body. Combined with the large bubble canopy, the 330SC provides unparalleled views of the flight environment.

While stability issues are primary in the design of the SC330, aerodynamics has not been abandoned. The aircraft hits the sweet spot when it comes to power-ascents to set up for a roll, and has the right drag profile to allow the plane to use drag as part of its maneuvers to result in some physics-defying moves.

Its advanced design includes a full carbon fiber wing assembly which integrates the fuel tank within, built strong and able to  remain rigid with a steel roll cage that adds to the ability for the wing and body to withstand sustained 10G maneuvers.

Lancair Evolution - Best Experimental for Seasoned Pilots

The Lancair Evolution is fast, and built for pilots who know their way around speed and sophistication. From the moment you climb into its p[lush leather cockpit the luxury and advanced capability of the plane is evident.

The plane, while advanced, is easy to operate. From this perspective, a newbie can handle it. It’s as easy as driving the minivan to the grocery store. Even setting the power for takeoff is a breeze. Just key in your gross weight and the onboard computer calculates everything, including how much power to tap from the engines when the time comes.

In fact, the engines are not even physically connected by a cable or a push rod, it's connected by data cables to a computer. The computer gets the pilot’s input based on where the pilot places the throttle, and the computer tells the engine what to do based on environmental conditions.

When you’re using your experimental plane to get from point A to point B, and you want it to just get you, your passengers, and your cargo there, there is nothing better than flying the Lancair Evolution.

This plane is the best experimental plane for seasoned pilots because it is fast and it is as fully automated as you could possibly want it. The only thing it can’t do is taxi, takeoff and land by itself.

The Evolution is so powerful that if you don’t already have a good understanding of speed and timing, and a sound understanding of navigation, pressurization, turbine operation, it is going to get away from you and that is more likely to happen to a low-time newbie than an old hat.

Most of the aircraft is fully automated. You can program the auto pilot like a corporate jet pilot programs the FMS on his flight deck. Everything is at the push of a button or mouse-like controls on a digital screen. The cockpit is a full glass cockpit with advanced data and weather at our fingertips.

It’s so advanced, it's hard to believe that it is built from a kit. Afterall, not every kit plane can reach 270 knots (true airspeed) at FL280 carrying four occupants and golf clubs. And with all that power and reliability of a turboprop providing the power for thrust and pressurization, the feeling of having a Pratt and Whitney PT6 provides incredible comfort.

The flight deck is so advanced that it is possible to add autothrottles to the already-included FADEC setup. The auto throttles will allow you to set the autopilot for your climb, giving you the ability to set the climb speed and rate of climb while flying flat-footed  and hands free.  This is one of the major aspects of this plane that gets me the most excited - it's powerful and digitally advanced.

The Evolution is a serious piece of machinery. It can get you across 1,290 nautical miles - that’s like going from Key Largo to Boston on a full tank of gas in just under six hours. Non-stop.

And since it's powered by a turbine, you get bleed air de-ice systems. At 29,000 feet, you won't get into icing that often since going around towering columns of visible moisture that can be easily avoided since you have satellite weather feed on board.

Then there is the ability to perform like a mid-size jet, but when you return to earth, it behaves like an ultralight with the ability to get down and stop in less than 1200 feet of runway. Take-off is the same. It just needs 1200 feet. And since it can land on turf, you can fly it from the backyard of your beach house in Florida to the clearing near your cabin in Massachusetts.

Pelegrin Tarragon - Best Overall

The Pelegrin Tarragon is arguably the most fun experimental plane to fly. It is simple, with just the necessary VFR equipment installed, it seats two in tandem. While it's not fully aerobatic, it is a lot of fun to fly with the ability to do Lazy-8s, chanedells, loops, barrel rolls and even powerful enough to do knife edges.

Completely built from pre-preg carbon, the aircraft can handle significant loads in flight. The fuselage, from firewall to strakes is made as a single unit that is then mated to the cantilevered wing resulting in structural strength and flight stability that is uncommon for aircraft in this price range.

There are two reasons the Tarragon makes it to the list of the best experimentals, and specifically for the plane that is the most fun. The first reason is that the Tarragon is an absolute beauty and those who love the attention to detail will be pleased with this aircraft as every inch of it is meticulously molded and machined.

The Tarragon’s parts and panels are built to within tolerances of ten-thousands of an inch, giving them a snug fit when putting it together. Once painted, the Tarragon looks smooth and lends itself like a canvas to an artist to be painted on in any color scheme you see fit.

The second reason the Tarragon makes it to the list is because of the absolute pleasure pilots feel when flying this plane. It is as easy - or easier, to fly than the first primary trainer most pilots have stepped into.

The forward seating position is snug, giving the pilot a powerful connection to the plane. Sitting precisely on the centerline of the aircraft, and very close to the aircraft’s center of gravity which allows the pilot to feel the plane pitch and roll around him. Flying it for a short while can very quickly give the pilot a good feel for how the plane behaves and reacts.

When it comes to doing aerobatics, where you sit relative to the center of gravity determines how much you feel the plane. In essence, this is the only plane I can safely say, looks, and flies like a fighter jet. The fabricators have done such a good job of designing and manufacturing the fiberglass panels that the plane has no rattle and looks amazing, without any break in reflection lines - usually indicating poor assembly, workmanship, or molding.

Once you retract the gear, the Tarragon wants to do nothing else but fly so it accelerates quickly toward its screaming 190 mph top speed and climbs at its regular 2,500 feet per minute to get to its ceiling of 25,000 feet in just ten minutes from brake-release. But what is really amazing is that all this sounds like it will guzzle fuel. But it doesn’t.

The Tarragon is one of my personal favorites not because it costs about $50 an hour to fly, excluding purchase costs. But that number tells me how efficient and effective this plane’s design is. And, that is important to me. It sips just 4 - 4.5 gallons per hour and still gives me 190 miles per hour and 11 hours of endurance.

For a new builder, the precision of the fit will make it tremendously easy to put together. There are no parts that you will have to fabricate yourself. Everything is in the box. Even the engine and the prop. You have a choice of three engines, and there is the rumor of a turboprop engine being considered.

In my personal opinion, no matter how inexpensive this plane, how sleek it looks, or how little fuel it consumes to burn the airways, this plane is my personal favorite because it is just a pleasure to fly. It makes even the novice look like an ace aerobatic pilot.

Velocity V-Twin - Best Experimental Twin

Then there comes the time when you want to build yourself a twin engine aircraft. Whether it's for the surety over bodies of water, or you just like the sound of a twin telling you that you have two of everything. Whatever your reason, there is only one twin engine experimental aircraft that will come close to sweeping you off your feet and that is the Velocity V-Twin .

It looks like something out of a futuristic James Bond movie, and so right off the bat, the looks make it a winner. Most people who first look at it mistake the V-Twin for Beechcraft’s Starship with the twin pusher configuration and forward canard.

The design is one that would work well for new pilots, giving them the comfort of an added engine, and the comfort that a canard-configured aircraft like the V-Twin is next to impossible to stall (as its stall speed is in excess of 100 kn) and that makes it next to impossible to spin.

This Twin looks and feels like a Caddilac. Even the process of getting in is easy, and just because it's an experimental doesn't mean it has to look and feel like it was built in a garage. It doesn’t. It looks like it was built in a master craftsman’s lab.

Coming back to it looking like a Caddilac, it begins as soon as you walk up to it and pop the door. It’s a gull wing, and that means you don’t have to be a contortionist to get into the plane like most other experimental planes make you do. Don’t get me wrong, I love tight cockpits for aerobatic stuff, but when I am out with the family or taking a trip, comfort and redundancy are my main concerns.

The V-Twin satisfies both accounts.

The leather interior and padded ceiling go a long way in making it aesthetically a winner, the extra sound-proofing does a lot to absorb the sound, which is already minimal since the engines and the props are in the rear and as you fly forward, the frequency you are exposed to is less invasive.

Speaking of sounds, the vibration levels are pretty well muted as well. Not only are your ears spared, but so are your tactile perception of vibration since the composite structure insulates the cabin from aerodynamic and mechanical vibration to a high degree, keeping the cabin cozy enough to enjoy the in-flight entertainment that you can opt for in the avionics package.

Even with the added capacity you get to carry four adults and luggage with full fuel, the V-Twin will still hurry along at 185 knots (true) with just 75% horsepower. That should tell anyone who is observing that the plane has to be sleek enough to slip through the air for it to be able to get those kinds of numbers. And it is.

The thing that makes this aircraft the best of the experimental twins is that it does not fly like a twin, especially when one engine quits. Look, the whole point of getting two engines, aside from having two of everything while paying for two of everything, is about playing the numbers.

The odds of both engines quitting is rare and when one does, you have the other to keep you aloft. But people are scared away from twin engine aircraft because the moment one engine quits, most planes want to turn into the dead engine and roll toward it and make it harder to fly. Uncomfortable, I know. But that's because most twins have their engines out on their wings pretty far away from the centerline, and that creates a greater moment.

The V-Twin’s engines are closer to the center line and as soon as one stops generating thrust, there is some yay, but easily managed. Flying around to the nearest airport with one prop feathered, is a non-event on this experimental twin and that is one of the main reasons the V-Twin makes it to this best list.

Hummel H5 - Easiest Experimental to Built

And finally we have the best experimental plane that is easy to build and the least expensive of all the planes on the list. For under twenty grand and 1000 hours of build time you can be up and flying in a Hummel H5 .

The Hummel H5 is a low wing, single seat, single engine aircraft. If you have never built an experimental plane before and you’d like to dip your toes into the shallow end of the pool, this is the plane you want to get.

But if you think you are a little more along in your building skills, Hummel actually offers three options. The easiest is what comes with blanks. Blanks are sheet metal pieces that are all cut and ready for you to assemble according to their highly-detailed plans. But if you like, they will just sell you the plans, and you can do everything from cut the pieces, weld them yourself and put them together. Which you choose depends entirely on how skilled you are in metal work.

Putting this plane together will bring about hours of fun but less challenges as they are pretty straightforward. It should take someone with average tool skills about 800 hours to build it out, if you take the least complicated option that Hummel sells. If you just buy the plans, it will take as much as 3000 hours of work.

Once the plane is built, you will find that it's a single seater that has ample baggage allowance. A respectable 1000 foot per minute climb and a better than expected 130 mph cruise up at 7,000 feet is enough to get you to enjoy all the golf clubs in a five hundred mile radius.

Coming back to the building. The Hummel H5 makes it up to the top of the easy to build list for the simple fact that it is the only one on this list that uses a car engine, a VW engine to be precise, which you can get easily.

The other reason that contributed to the H5 making it to the top of the list is that it is made of all metal. From the structural tubing to the sheet metal skin that covers everything from the wings to the fuselage and control surfaces.

The beauty of working with metal is that it has a lower learning curve compared to learning how to work with composites. And, most folks are already set up or have workshops they have access to that can weld and shape metal more so than shape composites.

As far as flying the Hummel H5 is concerned, anyone with just 25 hours and a Recreational Pilot’s License will be able to pull it off. Aside from having a stick instead of a yoke, the plane is as simple to fly as an old barnstormer.

The flight characteristics of the H5 are unexpectedly brilliant.. For something that is as simple as the Hummel, it flies more straight and true than I would have otherwise anticipated. and handles on all three axes with such precision and grace that pilots are usually surprised. It is well balanced and positively stable.

The cabin will accommodate a stature that is 300 pounds and up to six and a half feet tall. Anything larger than that and you will have a little problem fitting into it or enjoying the plane. Likewise, its maximum gross weight clocks in at 850 lbs, a remarkable feat given how small the aircraft is.

What's a Y-Tail?

 

Sonex Aircraft's and aircraft models all share a very special feature: the Y-Tail! The Y-Tail is our unique version of the V-tail that many pilots are familiar with. What makes it a Y-Tail? The rudder! Y-Tails feature not-only a V-tail set of mixed rudder and elevator controls, but also a small rudder at the base of the tail, changing the shape of the V-tail to resemble the letter "Y." Y-Tails not-only make Waiex, Xenos and SubSonex aircraft look cool, but they also offer superior handling vs. conventional V-tails, offer a simple way to drive tailwheel steering, and gives the exhaust of the SubSonex turbojet engine a place to go.

Incredible Four-Seat Comfort, Speed and Capacity.

experimental kit planes

The performance, handling and cost of the RV-10 make it the obvious choice in the limited field of four-seat kit airplanes, and a viable alternative to four-seat production airplanes – singles or twins – as well.

The RV-10 is a true four-person airplane, not just an airplane with four seats. It will carry four FAA standard adults, full fuel and sixty pounds of baggage while remaining at or below max gross weight. The cabin accommodates four full-sized adults. Both front and back seats will hold people 6’4″ tall and provide them with truly comfortable leg and headroom. Pilot seats can be adjusted in the cabin while seated. Composite gull-wing doors let the occupants board from both sides.

If your mission includes more than two people, and you like airplanes that perform and handle well, you really owe yourself a ride in an RV-10.

experimental kit planes

The RV-10 is designed to fly well on the bulletproof six-cylinder Lycoming O-540 engine, developing 260 hp. In our prototype, power is provided by a fuel-injected 260 hp Lycoming IO-540.

When many pilots say “performance” they really mean “speed.” The RV-10 is a fast airplane – it will cruise just under 200 mph – but speed is only part of the story.

The RV-10 derives its high cruise speed from a clean, light airframe instead of from a big, consumptive engine. This means cruise at lower speeds can be very economical. Company pilots often choose to cruise at 50-55% power and take advantage of the economy available there. At 175 mph, the RV-10 is covering more miles per gallon than most of the luxury cars, pickup trucks and SUVs it is flying over.

RVs are known for short-field capability and the RV-10 is no exception. Even at gross weight, the RV-10 can operate out of very short runways and climb well at high density altitudes. At the end of a flight, the generous wing area, big slotted flaps and robust steel rod landing gear allow the RV-10 to land at virtually any small airport — grass, gravel or pavement. If you can land closer to your destination, you can gain a lot of time over “faster” airplanes that must use big paved airports a long way from town.

Occupant protection is an important design criterion. The composite cabin top provides roll-over protection. Like all other RVs, the RV-10 has impressively low stall and landing speeds. If necessary, it can be safely landed in very small spaces at speeds that give the occupants the best possible chance of escaping injury.

The baggage compartment will accept 100 pounds of “stuff” loaded through the baggage door on the left side. If fewer than four people are traveling, the rear seatbacks may be removed in a couple of minutes for extra baggage space.

Up until the point at which the RV-10 was conceived, Van’s Aircraft was a two-seat aircraft company. Over time it became apparent there was a real market for a four-place RV. If we’re being honest, the decision to create the RV-10 was a big one, with some significant risk that represented stepping outside the then-current footprint of the business and into a new segment. The decision was made to invest the time and effort, and the company dove right in.

In the end, it worked out – and quite well.

With the mission of carrying four actual, real, grown adults and a full load of fuel, plus some baggage, the RV-10 was designed taking into account a number of things we’d learned from prior models. The metal portions of the kit were planned to be totally matched-hole, similar to the RV-7/9 kits we were already selling. We hoped to make the standard-build kits even easier to build, and of course we knew we would eventually offer RV-10 QB kits.

We also knew the wing would have to be a different design than we’d used previously. We’d had some recent experience with thicker-chord, high-lift wing designs in the RV-9/9A. Taking what we knew, a new airfoil was chosen to best meet the requirements we’d set forth while still ensuring we nailed Van’s signature “Total Performance” criteria. It had to perform like an RV, and it had to safely carry a real four-person load.

Ask any RV-10 owner or pilot and they will tell you, we hit that target.

If you were one of the folks who called Van’s at about 8:30 in the morning on May 29, 2003 and the phone rang and rang… Well, we had the best possible excuse.  Most of the company was outside, standing along the taxiway watching Van taxi the brand-new RV-10 to runway 35. At about 8:40, the big six-cylinder spooled up (quietly, with that big muffler) and the airplane was in the air in about 450 feet. Takeoff and climbout certainly looked like an RV!

And the rest, as they say, is history.

Flight attendant reveals secret hack to get the best meals on a plane: ‘there is a seating strategy’.

Here’s a tip that’s taking off.

A flight attendant admitted that there is a “seating strategy” behind meal service on a plane — and that some rows hold an advantage over others.

“Often meal service will begin at the front of the cabin and progress to the back,” Joyce Chan of Cathay Pacific airline recently told Delish .

A flight attendant explained that there is a distinct "strategy" in how airlines serve meals.

“Choosing a seat towards the front may increase your likelihood of being served earlier.”

Perhaps unsurprisingly, being up front in a higher-class seat also provides more meal options that can be preordered to a traveler’s liking, she added.

And the opposite can unfurl for folks seated in the far back seats in coach, as they are sometimes forced to pick from whatever is left when food service eventually gets to them.

Choosing your seat likely has influence on the type of meal you are served on a flight.

That’s why travel and food expert Melissa Leong suggests bringing your own food from home — or at least doing a little research ahead of time.

“Having an idea of what you might be served can help you decide whether it might be best to pack your own snacks, or just sit back and enjoy the in-flight service, such as it is,” she wrote last fall.

Another expert says it may be worth passing on airline meals.

“Mini magnums for dessert? Yes. A dish of food whose individual ingredients can no longer be distinguished? Maybe pass.”

She suggests packing sweet and savory snack items, plus yogurt or fruit smoothies in small containers to clear security limitations.

However, if you’re stuck needing to eat on a plane, Charles Spence, an experimental psychologist who focuses on how environments impact taste at Oxford University, has some recommendations.

Certain flavors change up in high altitude.

“Anything with umami taste, so Parmesan cheese, mushrooms, tomato, etc., and, of course, to drink a bloody mary given the double dose of umami both from tomatoes and from the Worcestershire sauce,” he previously told The Post . 

As for drinking, go with wine made at a high altitude rather than sea level as it will taste similar at cruising height.

“I would also pick wines with a sweet fruity nose, as this may withstand the conditions in the air better than a tannic oaked wine,” Spence added.

Air Racing: A Report

experimental kit planes

With the announcement of Roswell, New Mexico , as the new home of the National Air Races, it seems a good time to give an update on the go-fast crowd.

Change is the operative word, as the Reno Air Racing Association (RARA) and their National Championship Air Races (NCAR) at Reno-Stead were for decades the central characters in what was really a loose confederation of sanctioning bodies and classes. With the decline of the big-iron Unlimiteds and then the huge casualty of Reno-Stead last year, that confederation loosened with the various classes both considering their futures individually while at the same time hoping RARA could find a new place for the big, multi-class NCAR shindig.

Ultimately this could be good for the sport as there could be more racing in front of more people while still having the big NCAR jamboree. And now that RARA has committed to Roswell that one big event seems a certainty, plus some of the classes are already putting on events elsewhere on their own.

At our deadline, details on the September 2025 NCAR event in Roswell were essentially nonexistent. Speaking with RARA’s Greg Gibson just prior to the Roswell announcement, it was clear that whatever form the National Air Races take at what turns out to be Roswell, there will be some continuity with the old Reno paradigm. But more importantly, “We’re not picking up Reno and putting it somewhere else. There will be comparisons, sure, but the goal is not to replicate Reno .”

This is the right attitude, of course. Reno was ideal for air racing given the relative open land north of Stead Field and the vibrant nightlife of Reno on the south. Roswell has more open land but not the nightlife, but if different geographically, RARA says they are open to new possibilities. Considering many critics found the RARA show grown a bit stale then some changes could be welcomed. Easily applaudable items on RARA’s shopping list have been allowing fly-in spectating, enlarged recreational vehicle camping and increased hangar space, and at first glance Roswell might offer these improvements. Some of the thornier issues surrounding procedures and the business side of the event are not as clear and in other ways culturally ingrained, so I’m not getting the tailwheel in front of the spinner on this one and reserving my opinion until after the NCAR resumes. But a change in venue often loosens a cascade of follow-on changes, so we simply need to wait and see how the Roswell NCAR is assembled.

We do know that Roswell Air Center offers the expansive room associated with an ex-Strategic Air Command base. Built during WW-II as Roswell Army Airfield, it made the news during the 1947 Roswell UFO incident, explaining the alien and saucer motif spread around town. The field then expanded into the Walker Air Force Base during the Cold War, explaining the 10,000- and 13,000-foot runways suitable for loaded B-52s. Those huge runways and associated hardstands remain and should provide a comforting safety margin for air racers. Field elevation is 3671 feet and there is an operating control tower.

We can also observe Roswell is quite off the beaten path, especially by airliner, and with a population just under 50,000 this isolated town is not awash in hotel rooms. Expect a mainly local crowd at first, although the races would make a fine road expedition, especially for motorhomes and other campers. To put it in perspective, Roswell is approximately in the center of the Phoenix, Denver, Dallas triangle; the closest airline service seems to be Albuquerque, New Mexico, a three-hour drive. Naturally, those of us sporting cross-country airplanes see Roswell as more centrally located than Reno to much of the U.S. and the desert southwest is a great place to fly.

The truly important point is the big, all-classes NCAR will resume in 2025, including a pylon racing school (likely in June 2025) at Roswell to vet every pilot on the new courses. RARA is planning on running all seven existing classes, and we can note this will be at a density altitude, in a dry climate and on course lengths similar enough to Reno’s that no meaningful technical changes should be necessary to the race planes.

A Class Society

Historically, RARA has acted as a promoter providing a venue and business umbrella for the National Championship Air Races while each aircraft class is self-defining and regulating. Class rules and organization are provided and adjudicated by each class, meaning there are many cooks in the air racing kitchen. If a bit messy (ha!), this organizational hydra gives flexibility, so without getting lost in the details it definitely merits looking at the classes individually because the reality is, when Reno was lost the classes could no longer ignore they were really on their own. This was spooky as suddenly there was nowhere to race, but also unshackling as everyone was free to invent their own future. In this brief overview I’m ignoring the T-6 and Jet classes as they are culturally distant from this magazine, and the same is true to a lesser extent of the Unlimited class. Suffice to say all are welcome with RARA, and none have made more than cursory explorations of running outside of RARA’s National Air Races. However, the Sport, Formula 1 and Biplane classes are germane to Kitplanes and each sees their future running both the NCAR and in their own events outside the RARA umbrella. Organizationally this would make them like the STOL Drags , which has always done its own thing and only performed tangentially at the NCAR.

Sport Class

Easily the most organized of the pylon-rounding classes is Sport . I’ve previously chronicled their impressive two-year growth into an incorporated group with their own Accredited Race Organization (ARO) status with the FAA; four approved racecourses in Las Cruces, New Mexico, and Madras, Oregon; their own Pylon Racing Training Camp ; and at our deadline two demonstration races in front of the public. Sport includes everything from stock RVs to 400-mph Glasairs and Lancairs, and their culture is heavy on formation flying, a slick presentation and safety-first attitude. They’re also the class running current airframes and engines people can relate to and are best situated to embody air racing with a contemporary audience.

Not incidentally, Sport is the only class to put on any form of pylon air racing since Reno’s demise and at our deadline was scheduled to hold another race at Las Cruces this October. Expect to see Sport continue to branch out to multiple venues along with supporting the NCAR, and don’t be overly surprised if another class makes overtures to run at a “Sport event.” It’s possible, although any other class would have to do things the Sport way, and that might be a step too far for some. Sport is not really interested in standing “racehorse” starts, for example, which seems problematic for F1 and Biplane.

Formula One

With an immense legacy spanning back to the immediate postwar era, Formula 1 has been incorporated (as a 501(c)3 like the other classes) since the early 1970s. Furthermore, they have relatively recent experience racing internationally in Spain, Tunisia, Thailand and elsewhere under the auspices of a promoter now divorced from the class. And in fact, F1 sees renewed international racing as their best immediate option. Have no misunderstanding: Like Sport and others, F1 desires to run at Roswell, but in the meantime they are looking offshore, saying the financial and especially the insurance climate is far more workable outside the U.S. So far F1 has not applied for ARO status with the FAA and therefore in the U.S. needs to run under a sanctioning ARO authority—RARA in practical terms—although any ARO such as the Sport class would do as far as the FAA is concerned.

Caught in their chocks last year due to an intramural legal squabble, the Biplane class was essentially disbanded when the final Reno NCAR ran and so sat out 2023 in shambles. Reinventing themselves completely and formally organizing for the first time, most of the strut-and-wire crowd recently voted themselves into the all-new BARC—Biplane Air Racing Class—as a 501(c)3. They were busy writing bylaws, operations manuals and possibly working toward ARO status at our press time but had no concrete plans to run other than with RARA at the new NCAR.

A non-pylon racing incorporation with ARO status orbiting well outside the pylon racing culture, the STOL Drags has been unaffected by the turmoil within the NCAR and has continued their own series of events across the U.S. Expect them at Roswell as they are a crowd favorite.

All Together Now?

While air racing had the luxury of one big event with Reno for six decades, and even with all racers eager to see the big NCAR tent continue, the loss of Reno and the year hiatus of the NCAR has forced new thinking throughout the racing community. Specifically, each class has considered where and how it could race outside of the NCAR. It’s a tall order putting on your own air race, but given strong leadership willing to work long, hard hours and a cohesive attitude among the racers it’s (almost) possible. Cities are willing to host such events, the FAA has been very helpful to everyone in the pylon community, but insurance …isn’t playing. Some say at any price, others say at an affordable price, but the reality is only demonstration races (scripted results) have been run since Reno 2023 due only to the lack of insurance. RARA is adamant they can get insurance for Roswell, and given the sponsorship possibilities, likely input from Roswell the city and the state of New Mexico, plus the gate receipts the NCAR can possibly draw, they likely can foot the approximately $1+ million insurance premium. Other, single-class races not so much. Longer term regulatory reform (state caps on liability payouts) and other mitigations could make insurance more achievable for everyone, but we have to get there first. One idea yet to be tried but agreeable in theory to the Sport, F1 and Biplane classes is club racing. That is, private, no-spectator, no-purse racing as widely practiced by all other motorsports at the amateur level.

All turbulence aside, air racing is continuing. There are too many people with too many airplanes in love with the sport for it to fade away. It’s a fascinating outlet for amateur and pro builders alike to experiment in, but keep an open mind as to where and what it will look like. Next shot at the pylons: Sport Class at Las Cruces, New Mexico, Oct. 17–20, 2024 .
