i’m new at it. but i bought f450 guadcopter. i connected everypart shown as youtube video. but still motors not rotating. in mission planner radio calibration and anything else works fine. battery voltage is 11.4
I’m assuming a 3S battery ?
Mission Planner does pre-arming check and won’t arm if something wrong, is it reporting anything?
How did you calibrate the ESC’s ? the mission planner is usually useless
If still having problems send us some sketches or photos of your connections
