HI Guys,
I know it is written a hundred times in the thread, but after reading and re reading, I'm still stuck. I built a Quadro, with Arduino mini equivalent self-made board and an original WM+NK combo. Motors are robbe BL2827-34(760Kv/9A) with Gaui 8'' colorfull props. Frame is from Jakub (foldable quad frame). ESC's are PowerHD 12A. It flies OK with this config, but the props are I think too small, it hovers just at a little above 3/4 throttle. So I Changed the props to 10x4.5 (Also from Gaui). I balanced the motors and the props and added dampening to the WM+NK. The problem is that with these new props my quad is not flyable. At P=4 it start oscillating heavily after takeoff. I tried to lower P to 2.8, and it helped the oscillations (not cured, but helped) however it become very unstable. Any ideas how and what to change ?
