Some pilots love to whirl their wings over their heads. Many others like the idea of rotary flight — offering short takeoffs and landings plus ease of operation in windier conditions. A majority have not (yet) acted on their interest but perhaps they are waiting for the right aircraft, maybe one of these.
One is a very light coaxial helicopter from Russia. The other is a single place gyroplane from Poland.
Micron-3 Coaxial Helicopter
Have a glance at the RD Heli’s Micron-3 ultralight helicopter. This is like no other ultralight helicopter I’ve ever seen, although the idea of coaxial is not new.
History suggests coaxial rotors originated with Mikhail Lomonosov a very long time ago, according to Wikipedia. Over the years, many helicopter models have emerged but none so compact as Micron-3
Coaxial rotors are a pair of helicopter rotors mounted one above the other driven by concentric driveshafts, with the same axis of rotation, but turning in opposite directions (contra-rotating; see graphic).

All Carbon Fiber (Structure) Part 103 Ultralight Aircraft — Corsair is Coming to America
Most ultralight aircraft (officially: “ultralight vehicles”) are rather simple constructions. They must be to stay within the tight constraints of a 254-pound maximum empty weight.*
That’s not a negative comment about them. Actually, it’s the opposite.
To build a flying airplane that weighs less than the engine alone on a Light-Sport Aircraft, a designer has to be unusually clever.
All aircraft are constrained in weight by the laws of physics. Ultralights are further constrained by regulation.
A key way to keep an aircraft light is to keep it simple. Indeed most 103 ultralights are quite basic. However, as years passed some engineers have found intriguing solutions. I recently wrote about the composite Swan. Why not one using extensive carbon fiber?
Carbon Corsair
German developer Jörg Hollmann took a different approach, one that consumed a few years of effort.
He wanted an aircraft that resembled the famous World War II F4U Corsair fighter.
Try and Fly TriFly — Kolb’s Wonderful Single Seat Light Aircraft Goes Both Ways
Some pilots are wary of taildraggers. This is hardly surprising since only tricycle-gear aircraft have been used in primary flight instruction dating back into the 1970s. Most pilot have no experience with taildraggers but nearly all have heard of the dreaded ground-loop tendency such gear configuration can allow.
Indeed, when investigating insurance for a taildragger, you will have to prove you have some experience or get training from a suitably-experienced instructor — and you won’t find many able to help you.
How about if an aircraft went both ways? What if an affordable aircraft allowed you to fly with tricycle gear but permitted you to practice your taildragger technique yet still use the nosewheel’s self-straightening capability if you start to get a little “sideways” (literally or figuratively)?
Kolb Aircraft has an answer.
Kolb TriFly
Producers of Part 103 aircraft, such as Kolb Aircraft report consistently strong business for the last few years.
Swan Producer Adds Two-Seat Version to Popular 103-Compliant Ultralight Aircraft
We live in an age of sophisticated two seaters, a large flock of wonderful aircraft of every description. Such two-place flying machines lead in sales and perhaps that’s to be expected. Around 80% of light aircraft buyers prefer three-axis fixed-wing aircraft. This is hardly surprising as that’s what nearly all pilots have used for primary training since the ’70s.
To select another aircraft type means going out on a tree limb. This is especially true with what I call “alternative aircraft” — weight shift trikes, powered parachutes, motorgliders, and gyroplanes. It would include lighter-than-air, too, if we had more than a single entry.
However, some three-axis fixed wingers also disregard Part 103-compliant aircraft. Some say, “Those things are flying lawn chairs,” by which they try to disparage the category hinting they’re too “flimsy.” Most who say this probably never sat in one let alone flew one.
One entry I’ve written about (see my earlier report) appears to have be viewed differently, perhaps as it has a full enclosure and is built of composite materials.
Wanna-Be Oshkosh Week — Dynon at 20 Offers Sessions During Would-Be AirVenture
Perhaps it’s too bad the airplane sellers can’t do something similar, but avionics developers have found a way to be Almost-at-Oshkosh and they invite you to join them. See Garmin’s approach here.
We’ll join our friends at Dynon while they host their version of “Virtual Oshkosh 2020” and while we’re at it, we can congratulate this Washington state company as they celebrate 20 years. ??
Let’s hop in the Way-Back Machine and beam ourselves to late 1999. The world was an analog place. Sure, we had PCs and cellphones but both were pretty clunky, costly, and slow by today’s standards. Digital cameras were just becoming accepted and nobody took pictures with a phone.
Yes, the World Wide Web was available (for a whole five years) but, honestly, it wasn’t that fascinating a place back then. I know, as this was the same year I started building ByDanJohnson.com — I hope you’ll believe me when I say it was tougher then than now.
Garmin Announces Remote Learning As Offset to a Summer Without EAA AirVenture Oshkosh
Garmin is going to Oshkosh 2020! No, wait, that can’t be. Oshkosh is going to Garmin! Nope, that’s not right, either. Ah, how about Garmin simulating being in Wisconsin, in effect, bringing a virtual AirVenture airshow right into your home. Now we’re talkin’!
Actually, this is rather cool. I don’t know about you, but when I go to Oshkosh, I race around from display to display getting the latest news. Because hundreds of airplanes and engines are located outside, that’s where I’m focused. Getting inside the buildings to visit hundreds more displays generally happens only for specific news. Almost never do I get to explore avionics or flight planning software.
That’s all changed for what would be Oshkosh 2020.
Virtually Yours…
The team at Garmin has cooked up an online version of a regular occurrence at their AirVenture display where they deliver seminars and offer experts to help explain or debug your gear.
Vintage Light Kit Aircraft Heaven — Checking out ScaleBirds’ Curtis P-36 with 5-Cylinder Engine
ScaleBirds is not your run-of-the-mill kit aircraft company. In truth, all kit builders are amazing to me.
People who labor for years to design an aircraft, craft methods for making the constituent parts, assemble it all, work out bugs in construction, fly the aircraft, then smooth any rough edges of its flight qualities, start producing kit components — and the manual it will take for a non-expert to build the kit (perhaps the hardest task) — and finally, start the effort of telling people about the airplane, market it, sell it — and the big one — try to turn a profit for doing all the preceding. Any way you cut it, birthing a new design is an immense project.
Sam Watrous, his son Scott, and their merry band of (mostly volunteer) ScaleBirders are not merely doing all the above. They are emulating vintage American military designs in reduced scale and trying to get the details right so the kit versions look as much as possible like the originals.
Kit Aircraft Are Up; New Sales Are Off — Recreational Aviation Copes with Covid
Our fastest-with-the-mostest partner tracks the health and performance of the light aircraft industry and is once again punctual. Datastician Steve Beste has proven his capabilities to collect the registration data quickly, accurately, and with an insider’s viewpoint. Steve is a trike pilot, so he is “one of us.” In his former life he was a database expert in the tech field explaining his great facility with these systems.
Here we are reporting facts for the period of April, May, and June 2020. Given the spectacular upheaval around the world, I’m happy to see the recreational aircraft industry holding its own fairly well. Reporting for the companies making larger, heavier aircraft, the General Aviation Manufacturers Association also reported sales are down. I cannot imagine anyone is surprised.
If I was reporting numbers for the restaurant, bar, hotel, airline, theater, sports, or concert industries it would be an ugly bloodbath. This report is far less glum and beaten-down than those enterprises.
