I was performing an autotune on my new Tarot X6 with Pixhawk 3.2.1 and short after a few roll tests it suddendly shots over to the right and chrashes in about 45° into the ground. Damage is repairable, but i dont want that this happend again.
Most of these are caused by motor sync issues where the auto tune request a sudden change in motor speed and that motor locks up causing the crash. Need motor speck info. Slow motors with large props seems to be the issue.
