Forgot about that clarification. Seems to cover it. As to basis of the supervisors call, I could only speculate, though I'd direct you back to the rules. Are the rotors carrying the weight or is it being carried by some part of the building?

Then our bumper is like 8 inches long so it was wiggling up and down but the prop stayed almost perfectly still maybe it made 7 or 8 revolutions while there. However im fairly certain that it was not producing significant lift.

In these circumstances, it may be possible for the lower rotor to fully support the helicopter. However, we cannot comment on every possible scenario or say definitively if timing should continue or not without seeing the actual flight. The actual determination for when timing stops will be the Event Supervisor's judgment call."

Then, in spite of the ceiling bumper being stuck in the crack, you say the copter is moving up and down. How is that possible for it to be stuck so that the top rotor won't turn but still be able to move up and down?

I am fairly certain of this because the whole copter moved up and down in the crack and after about 6 minuets it left the crack and flew down in the normal manner, as it would have had it not gotten stuck, and landed with a normal amount of winds left. This Leads me to believe that it is possible stop the rotation of the top rotor and still have a legal flight which lasts much longer than a normal flight. However one must find a way of stopping the rotation which does not support any of the mass of the copter.
