I am not new to pixhawk, just did few flights last month and they were perfect.
Now I am trying to make a new basic quad, using f450 frame, 30amp esc, 1000kv motors, 2200 mah 11.1v battery, 1045 props, and pixhawk 2.4.8 with gps, also using telemetry.
I did all the necessary calibrations, including accelerometer, compass(learn new offsets), rc calibration etc. I also had failsafe turned on, which was triggered to RTL when hitting 10.1 volts,GCS enabled.
I did my first flight and it failed, the quad lifted up, stabalized and then even when my stick was on 0 throttle, it kept on rising up and up, i wasnt able to disarm it. The quad was in stabalize mode. The quad fell on the ground wobbling and hurt my arm until i pulled its battery out.
Points to note are,
- I have pixhawk not on top of frame but in middle of frame, battery and gps mount are on top.
- After it fell, it showed bad battery on the screen of mission planner.
- The “H” (home location) was away from where the quad really was. I tried to arm and disarm multiple times but it always showed up on top of a building that was nearby and upon hovering mouse on H pin on the map, it showed “207”.
After that I did not fly the quad because i was too hesitant that it will again go out of control.
I am attaching few log files for your reference.
