Remember you really only have Fam 1-4 to get the whole hovering thing down
It's still all about attitude control - even in a hover. Th ebig thing in a helo is training your brain to understand the lag between what you are seeing and what myour response is with the hand that's on the cyclic. That just takes time. In the '57 there is lag between when you move the cyclic and you get any sort of attitude change - and there is lag between attitude change in a hover and when the aircraft actually gets enough momentum to start moving - the combination of all this just means you need to train your brain a little - but I never saw anyone - even flihghjt surgeon studs who eventually couldn't pick up the concepts and hover more or less successfully.
Also in the '57 this is the student's first experience with hydraulically boosted controls.
Keys to getting hovering down:
1. watch the studs' shoulder and body pisition as well as foot position on the pedals. Forearm should be resting on thigh, heels on deck, pedal should be underneath ball of foot, pivoting off the heel. Don't squeeze the black out of the cyclic.
Scan out and in - but not too close. Use forward and peripheral vision to pick up attitue changes.
Don't pump the collective - Powerchanges need to be relatively slow in a hover to avoid a. transient overtorques, and b. yaw/roll/pitch moments that you'll have to correct for.
Make sure you breath.
