Remember the Rotary Engine of the Sopwith Camel?
Engine Control was Ignition ONLY!

Here is a fascinating video explanation of how to manage the WW-I Sopwith Camel Rotary Engine, and fly it.

Imagine any one 'brave enough' to ride this thing...........   Let alone fly it???

Also, the Sopwith in formation along side the WW II Spitfire.
At the end of the video is the beautiful sound of that V-12 RR Merlin engine.
Turn up the sound and make sure you go full screen - enjoy!
