Default RE: Achieving realistic scale speed in model autogyros


ORIGINAL: ottogiro58

From my understanding, rotor RPM was less than 250 revs per minute. Seems that model gyro flyers could benefit from thicker, larger blades in order to slow their flight. I was amazed to hear that many gyros are flying with rotor revs at or above 750 RPM !!! "
The whole point of the autogiro was to let the wings keep moving fast so the aircraft could go slow. Slowing
the rotor doesn't slow the autogiro, the reverse is true. The full sized gyros at 200 RPM still had
tip speeds in excess of 200 MPH.
The stuff I'm flying can hover in farly low winds without prop hanging, rotor rpm is 1500.
