Hi guys,
This might well be my fault, but I'm having trouble with the self level on my 450. When you set a low throttle and move the quad around by hand the motors that dip do speed up as you would expect. But in flight it doesn't level itself at all. Flying with self level turned off is exactly the same (flys a bit smoother actually), it stays at the same angle you leave it at on the stick, and I have to flick it a bit to pull level.
Gone though a few setup guides and videos and can't see a problem with settings. Could it be a faulty board?
