Hello guys,
I have a custom made quadcopter X as shown in the link below, running ArduCopter 3.6.9.
A few weeks ago I had a problem during landing it in Loiter Flight Mode. When the drone touched the ground, it did not recognized the land complete, accelerated the motors, tilting the vehicle towards, damaging propellers 1 and 3. The vehicle did not have a downfacing rangefinder in that occasion (flight registered in log_1 file).
Today, I was flying the drone with a SF11/C lidar connected thru I2C in I2C2 Port, and again had a bad landing, this time in RTL Flight mode. Again the vehicle did not recognized the land, unstabilized and this time I had damaged propeller 4 (flight registered in log_2 file).
Could someone help me to find the problem please?
