Hi. I wanted to test my configuration for octocopter 15.55 props 1270mm frame with a drill on the bottom but it did 180 degree flip. Props and motors were connected correctly. ( Sry for the light, or rather the lack of it… )
The motors are also going to near max so the drone is either too heavy, or there is something wrong with the props/motors. Have you done the motor test to make sure everything is going in the correct order?
