Just finished up a new build, 90mm brushless. Idle throttle is fine, no flipping etc. When throttling up, I get these intense audable and visual oscillations. Not even off the ground yet.
When hovering for a second it looks like ?yaw movement, but it just sounds so nasty I land.
P’s on 10 doesn’t make a difference. Motors spin freely and the screws don’t appear to be touching the windings.
Little bit at a loss as to what’s going on.
