Hi all! today came the situation, when a drone at low speed crashed into the wall. Then the axis of one engine became tighter to rotate than others. Tangible beats and violations of the axis is not felt. the drone on takeoff overturned. what to do?
Is the motor harder to spin by hand as well? Are the propellers installed in the correct motor? Even if it isn't working like the rest, it should still fly, unless the brush inside got twisted and is hitting the cilinder inside.
