My understanding is that with the collective stick and trim at center position the idle up switch should not effect collective. On my heli the pitch goes negative when I "idle up". Do i lenghten or shorten the pitch control link? Thanks.
YOu are correct- it should be at 0 pitch when stick is in the middle. Shorten the blade grip links (keep count so you can return) by 1/2 turn increments and see what happens :0) I would set my blades for 0 pitch by doing just that and checking if there was downwash or upwash, when none you are at 0 pitch. It works :0)
