I inherited a Mantis Q. I have one issue remaining. The camera functions but the gimbal works very intermently. I removed the top cover and removed and reconnected the circuit board on the top cover. With the drone powered up and the remote connected the gimbal servo motor will run for 2 seconds and then stop for 12 seconds and then repeat until the unit is powered off. The gears/shaft does not rotate during the motor running. The camera is semi-free on the gimbal. I am brand new to this. Can anyone point me in the right direction?
