I have a quadcopter and it flies in stabilize or acro mode so good, but in loiter or auto mode it flips. The motors are spinning different in those modes. Motor rotations and order are true. Props are true. GPS seems good. What could be the problem and how can I fix it?
Could you do the motor test to confirm that the motor order and direction is correct?
When you push the “A” button the front right propeller should spin. “B” should make the back-right propeller spin. “C” should make the back left propeller spin. “D” should make the front-left propeller spin.
Also make sure that the direction matches the image for your frame. This autopilot is configured as a Quad X so the front-right propeller should spin in the counter clockwise direction.
Also make sure that you don’t have any propellers on upside-down.
Please also check that the arrow on the autopilot is pointing towards the front of the vehicle. The servo connections on the Pixhawk should be pointing towards the back of the vehicle.
Sorry, I thought I should describe them to Pixhawk. SunnySky x2814. 1155 propellers. 3.7kg. The trim value of motor3 was 1140 and I made it 1500 then it was fixed. So now it fly in loiter or auto mode. Thank you for your attention @dkemxr
I made al of those things. I do not know was it about that, but the trim value of motor3 was 1140 and I made it 1500 then it was fixed. So now it fly in loiter or auto mode. Thank you for your attention @rmackay9
