I've seen that... LOVE the smoke!!!!
The smoke is awesome. Do you think that the power to weight ratio with the turbine is worth while on that planes. Would it be able to do 3D?
It will but you have to be much more careful. You don't have the instant power of a gas engine... It's takes a couple of seconds for the turbine to come up on rpm...
Wouldn't the exhaust be so hot that it would cause the covering to buckle?
here is another video, around minutes 5-7 you can see the yak and it dose hover..
