Here's a Youtube Curtiss OX-5 Video of an OX5 being hand cranked on a Glen Curtiss Seaplane. This Curtiss OX5 Youtube Video shows the Curtiss being run up in a Curtiss Jenny Biplane. The video could be better but the sound is fairly good. It is amazing how clean these engines are considering much of the valve train is exposed and lubricated externally.
