In normal mode, it flies ok but have small and fast oscillation on the roll axis. on one occasion, one motor seems to have stopped for 1 sec. In position mode, it have the same small and fast oscillation on the roll axis and it cannot hold altitude. It will slowly drop until it touch the ground.
Please guide me on how to resolve the oscillation and alti hold.
Thank you.
