Dumb question maybe re Stall Turn
Your friend is correct. The torque produced by helicopter rotors is
proportional to their length - just as if you were to use a wrench on
a nut with a very long shaft, the longer the shaft the greater the
torque. I assume you are talking of a single prop engine stunt plane?
These are light and the thrust needed to maintain a static hover as
you describe is not great, and coupled with the short rotor length the
torque produced would not necessarily overcome the inertia of the

I've occasionally watched aerobatic displays and seen a maneouver
called a stall turn. *Now, I more or less understand how this works,
but there comes a point, just before the aircraft "turns around" where
it is momentarily stationary in space, pointing directly to the sky..
Impressive stuff. *Now, here's the crux: *My mate reckons the pilot
could hold the aircraft in this "head-up" attitude almost indefinately
as the prop is acting like a helicopter's rotor and it could
effectively hover in this attitude. *I, however, maintain that the
aircraft would begin to spin on it's axis if held in this attitude.for
more than a second or two.
Can anybody tell me who is correct?
