I was trying to test my custom quadcopter with an H frame with 16 inch props, the logs show it switched to RTL when I was throttling up the drone to takeoff then it rolled right, caught a prop into the ground and continued to tear itself apart. I cant figure out what caused it to initiate the switch to RTL. Any ideas?
The solution to most support problems it to read and use the “copter tuning process instructions” posted countless times in this forum. Or to press “Alt-A” in mission planner, the result is mostly the same.
This es especially important for large custom build frames, of for very small frames.
