I’m using quad x.
I have been trying to edit the lines:
outputs[i] = roll * _rotors[i].roll_scale +
pitch * _rotors[i].pitch_scale +
thrust * _rotors[i].thrust_scale;
File : MultirotorMixer.cpp
Function : MultirotorMixer::mix_airmode_disabled(float roll, float pitch, float yaw, float thrust, float *outputs)
But there seems to be no effect on the drone behaviour even after a successful compilation(make px4_fmu-v3_default) and upload(make px4_fmu-v3_default upload) thru the console.bat. The same commands show proper effect when used to edit quad_x.main.mix
