Why is this wonderful little machine 20 years old and I'm just now finding out about it? Legal issues? Production issues? Safety issuers? Let me know! Thanks! Gordon
While I don't fully understand coaxial rotor-wing flight as I do single main w/tail rotor helos, I'm thinking that 10,000 Soviets can't be wrong.... They've had coaxial flight with gunships and utility helps, and I'm pretty sure they all have autorotational capabilities. If you know something I don't please do enlighten me....!
the first full controlable helicopter was a coaxial (1933 Breguet Dorand gyroplane laboratoire), so nothing news...a coaxial helicopter can make autorotation, but less efficient (faster descend speed) as a single rotor because the rotors are much smaller, this explain why all Kamovs are twin engined...
Economy of power (25% for tail rotor), and dissymmetry of lift: «Coaxial rotors avoid the effects of dissymmetry of lift through the use of two rotors turning in opposite directions, causing blades to advance on either side at the same time» (wikipedia)
@Peter Chrobak -where did you buy your Coaxial Rotor Mast from? If you don't mind saying, I want to build me a small one, plus I have a perfect power plant for one thanks, and I know it's alot of work but well worth it!
So this was nearly 6 minutes of the helicopter spinning in circles and going no faster than maybe 20-30 MPH. Yet still... WHERE THE HELL DO WE GET ONE???
Just like a toy coaxial helicopter compared to a regular CP. Single rotor helicopter...the coaxial helicopter has super stability and easy to fly...but it's slow and can not deal with wind very well...
I have some of the original brochures and spec-sheets on the SkyTrac. Was very disappointed when it "went-away" - thought it had a potentially great future in agriculture, fire-fighting, external load operations, etc. Always wondered what led to the demise of the machine, but suspect (as is usually the case) their financing collapsed.

Scott Ruggels Thanks, Scott.... Answered all my questions and curiosity....

Of course it Autorotates, learn how a Helicopter flies.....

ehat is the name of the this powerful engin ? i wander!
Coaxial helicopters DO have the autorotation caperbility. 2 stroke motors or 4........Peter
What are the advantages of flapping blades over ridgid?

Ability to flap helps in rough air,rigid are very bumpy

Do you have the skinny on blue prints or any production parts for this aircraft?
looks like something you would see in a radio control magazine...

I think this machine dates back to the 1970s
This looks like a prototype. In any case the Russian company Kamov have been doing this for many decades.

Could I purchase copies of the brochures and spec.sheets you have? Thank you!

The Franklin explains why it sounds just like a 47.
any one have the contact details of peter chrobak ?
Excellent film footage and sound. The commentary could be better.
Maravilhoso quro uma como faz
That's a lot of engine for a single seat helicopter, unless it's role is similar to a Kaman.
fantastic
Great Content! Co-axial is the future. Wonder why its taken so long to catch on?
Because rotor blades cost $10k a set and come to with life expectancy in hours.
90% of helicopters are still the tail rotor design, coaxial has its problems, they havnt caught on.
Another issue is yaw control, no prob with tail rotor and they tend to be taller.
Very Cool!
ufoengines hola suscribete a mi canal yo are lo mismo no cuesta nada 🇩🇴🌎
don't get to close to people, and people, don't get to close to the helicopter.
Let me guess, another company price them selves out of existence?
Its a Dam big machine just to take one man, nice though,
error. listen to the Speaker. It`s made to lift and Transport 5oo KGs + Pilot.OK?
