PROMARK VR DRONE Drone got stuck in tree. Fell 30’ from branch to ground (grass). Now flips at takeoff. Took propellers off. Compared motor speed. Have to make 45 degree angle to get all four motors to be close to same speed. What causes this? Eric
I have this problem too. I crashed my drone, and at first t worked but then started doing this. I did testing as well and posted a similar question. I do not know why it is doing this. I have tried resetting the drone but have had no luck. I believe he gyroscope is damaged, but have not figured out how to fix it yet.
check the gears on the motors one of the teeth could be broken
