Well the crack was from a not seated tile so it was rather large. Say 5 inches wide. 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.
Also if this is not allowable perhaps this clarification under the FAQs needs to be revised?

01/27/2011 - 22:26 Do both rotors have to be rotating for timing to continue?
No, there are many circumstances when the top rotor may stop turning due to friction or other causes and the power from the motor is transferred to the lower rotor. 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."
What would the basis of the Events supervisors 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.
