Getting a slight chirping noise during throttle adjustments. Motors are cool to the touch after flying. Am also getting a bit of drift in the roll axis on launch. It seems to correct itself once I stabilize things and hover. What causes noise like this? Should I be concerned if the motors are staying cool? Flying a 6s 5" qav-s.

a slipping prop can cause a chirping noise. so can a bearing that is starting to go. Both of those could cause some unexpected movement in the quad.
But some props just make a chirp when the harmonics are just right. usually the sign of a bent prop. and the roll in yaw could just be a tuning issue. probably I term being soft.
Hard to know for sure. Re-tighten the props first! 😁
