I don't have a lot of experience with commercial frames. But I did hold a genuine DJI F450 once and was amazed how flexible it was (flat plastic arms and spindly center plates). There have also been a couple/few other frustrated AQ users here trying that frame, over the last couple years. And I've seen the same complaint on other FC threads. I understand that the knockoffs can be even worse. OTOH, some people swear by them, hence the "YMMV."A plot of the ACC values should give an indication of vibration levels. Ideally with the copter stationary but not in "ground effect" vibrations (clear air under the props, like on a box or a stool).
