Anyone got experience with carbon props on the PV and where did you buy them? My PV was flying stable but last week i noticed some props where way out of balance and when i put other props on, it was flying stable again. The props are soft and quickly out of balance and the pv had jello effect and 1 motor was pulling to the left. I don´t want to buy new props all the times. On my hexa i never had any problems but they are too big for the pv and i don´t have motor prop caps yet. It doesn´t matter if they are not self tightening props because i never lost a prop with my hexa and they are not self tightening.
