Hi, my team recently won the NJ state Science Olympiad Tournament so we are going to nationals. We had a 2:12 helicopter flight wHich got us second place. I recently found out that it is possible to get much higher times if the top (free) rotor stops spinning once the copter reaches the ceiling and starts to spin again once the copter starts to come down. However Locking the rotor does not work as the motor stick still needs to spin. Essentially he rotor must get stuck to the ceiling under the lift generated solely by the lower rotor. We tried to just use tape which worked until it got stuck to tightly.

I was hoping you guys could help out.

Thanks,
