R22 Trim, (forward flight):
The cyclically varying pitch (necessary at speed to prevent a changing disc attitude called 'flap back' which would result from 'flapping to equality' if the 'flapping to equality' was actually required to eliminate 'dissimetry of lift') has max rate of pitch increase at the front (max decrease at the back) so the pitch link needs to be pushed up on the port side, the pilot does this by applying a small force to the right - or you can get the elastic band to do it for you by pulling the 'trim' knob up!

Nice to see a few people have been putting up a valiant (but feeble) fight against the distortions of the 'well intentioned' Lu!

(Hope you can follow that Lu!)
