Why FC keeps trim value at Manual mode?

Hello. Explain me why is my PixHawk sending PWM of 1500 instead of
1100 to the motor when I switch to manual mode and the throttle is in the lower position?
When I push the throttle up, the value goes up to maximum 1900. But in lower position it is 1500.
Thank you.

Calibrate your radio

Do you mean trasmitter? Everything is fine with it. If I set RCIN3 everything work as it should be.

Yes. Use the radio calibration screen in Mission Planner to set the min/max values that it’s sending.


That helps. Thank you sir, you are my hero!

I linked the instructions above. They are in the “first flight” / “first drive” section of the documentation. Read and follow the rest of that section carefully.
