Info from Licensor: "I mounted a key-cam on my RC helicopter's rotorhead (Three dee MP-EXL) to record my FBL rotorblades and synchronized the frame rate with the rpm (30fps = 1800rpm = 1 round per frame). The 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!"
