RE: Aileron Differential on a Bipe
Dunno Root, Much of what is known comes from the 'Aces High' book, the Camel instructor is non other than Capt. W E Johns, the 'Biggles' creator. Bits of the RFC pilots training manual can still be found, where you will learn how to do such esoteric things, as a 'correct loop', learn the 'proper landing method' etc., even some basic combat maneuvers. Otherwise read what modern aviators say about flying the reproductions, the Cole Palen (Rheinbeck) crowd should be able to help.
