I agree with Bill. This rule loophole needs to be closed if it isn't
already.

 

To muddy the waters further, there is a precedent in AMA Helicopter, going
back 45+ years. I'll now ask Jerry Murphy (now Chairman of the FF Contest
Board) to weigh in.

My understanding is that in the 2 state finals I'm familiar with the top
rotor locked into either a ceiling tile or a light fixture.
The copter then stayed there until the torque dropped enough for it to fall
free.

The kid I was helping had his copter hang the top rotor on a practice
flight. It took over 10 minutes for the bottom rotor to stop. In his case
the copter didn't fall so it wouldn't have been a legal flight (I guess).

So I don't think we're talking about an aerodynamic phenomena. The copter is
being supported by the ceiling - not by the thrust from the bottom rotor.
