that is so very efficient. it is like it makes a virtual air wing over the top of it. the forward force into the wind itself spins the turbine, so to fall towards the ground on a forward trajectory will force it to stay more into the air. and then you add your extra power. place 2 independent rotors, and you will have balance control, or else make dihedral with uni joint connection- only one motor.
In all the videos I've seen of this design, the craft has serious stability issues, particularly during or immediately after take off. Is this caused by the design, or it is just endemic to flying small remote craft in general?
Small aircraft down to 4" wingspan are no less stable than a Jumbo Jet. In this case, note that once in the air, the aircraft settles down nicely. That little bobble on take off may be due to the narrow stance of the landing gear and the lack of feel, seat of the pants, when flying an aircraft remotely. All your clues are visual.
That's not to say that stability could not be improved. I'd try some dihedral just as you find in a conventional wing.
When you test a smaller sized model of a plane, is it somewhat equivalent to testing the full sized plane in faster winds? For example a flat square direct in the wind, and then a quarter of that square (dividing each dimension by 2) in the same wind will receive only 1/4 of the wind forces.
i saw this in popular science a couple of years ago... what i find the most amazing about it is that the engine is just above an idle and it takes off

Great model! You must take som pictures so we see how you design it. Do you have drawings for the model?

@dadpups this wont be used for commercial travel, unless you want the flight to take 3 times longer....
