Whenever I do flips, it seems that the heli moves not evenly. Maybe cyclic rate is still to much, but it is very slow for my taste. In the log I get a lot of cyclic ring warnings. I set it from 130 to 150 and got less warnings, however 130 gives me 10° cyclic (measured) and is the maximum I can go without binding of elevator servo in upper direction.
Setup is 11° collective symmetrical, BLS 452 @5.6V with linkage mounted at 17mm distance (manual says 16mm), Rotortech 690.
The problems are in bank 2 with 1950 rpm.
Maybe this heli needs way more than 10° cyclic deflection?
