Flips on takeoff after crash

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.

Hi unfortunately the two questions about dorne flipping after hard crash is the gyro circuit on the main board is damaged. The gyro is intergrated on the main board in the drone which would require replacing. The other modules inside the drone is the altitude air pressure sensor above the battery box and the GPS sensor board mounted center under the top half of the drone body. The main module is available from Amazon online.
