I just moved from QGroundControl to Mission Planner. Main reason is the motor test function in Mission Planner. I first started with QGroundControl because I could not find my frame type “Dodeca Hexa Copter” in Mission Planner. I got an advice in this forum to change the parameter Frame_Class (in the Full Parameter Listing) to the value of “12”. I did that and I also changed the parameter “Frame_Type” to 3 (which is H").
I don’t get it working. I am unable to arm the copter motors I am getting all the time the same error:
PreArm: Check firmware or Frame_Class
