Helicopter rotor panorama. Camera on rotorhead.

I mounted a keycam on my RC helicopter's rotorhead (Three dee MP-EXL) to record my Edge FBL rotorblades (http://www.edgerotorblades.com/) and synchronized the frame rate with the rpm (30fps = 1800rpm = 1 round per frame). First results were completely blurred, except the blade, because of the scanning shutter. Then I mouted the cam vertically to optimize scan direction and the results are amazing!
