I usually enjoy and often admire your posts but sometimes I think you write
too much too quickly and make too many assumptions.

You appear to assume that a primary requirement of the motor is that the
aeroplane will not touch the ceiling. Surely the flight is not terminated
if the ceiling is touched.

You say that the propeller efficiency is highest at the start of the flight.
My propellers are certainly not designed that way.

Your statements on backing-off are not to clear but you would appear to
assume that the shape of a backed–off torque curve is the same as the shape
of part of a non-backed-off torque curve, and that is not so.

You have so much to contribute, please slow down a little! <smile>
