RE: THROTTLE CURVE
your stutters pretty bad too eddy
much easier to play with expo in your case, btw, those mirros are easy to get hold of, most rc shops that sell little clamps, helping hands cheap nicknack, etc etc, normally have some, if not i'm sure your local pain giver ( dentist ) will be able to point you in the right direction.
