PX4 QGC Was flying fine.
After installing bigger motors, and trying to again PID Autotune failed.
The instructions say to increase FW and MC_AT_SYSID_AMP by steps of 1 and trigger autotune again.
I did so (before taking off), position mode. Before I could even start Autotune, I switched to Altitude Mode- it flipped upside-down and crashed.
Now several parameters esp PWM paramaters are missing. Pressed/ reset the IO PWM and FMU reset pins , re-seated microSD, erased and reloaded firmware uploaded again. Checked the wires with ohm meter. Tried reloading latest saved working parameters.
Still no resolve. It boots up, although with alarms.
- Should that instruction say “steps of 0.1”
- Should I takeoff before increasing MC_AT_SYSID_AMP by steps of “1 .0”?
- How to get params working?
- Is a new microSD needed, and what format?
