Cams Gnome Rotary in Sopwith Pup replica at Omaka New Zealand

Video of the Sopwith Pup flown by Wayne Tantrum. It is a long taxi out to the runway and you will notice that he is blipping the engine to keep the rpm down. What you can't see is that there are 2 other aircraft formating on him and he is running the engine at the 1/2 ignition setting for much of the flight to reduce his speed to match the other aircraft.
