Commercial use: Yes

Runs a digital PID control loop at a 250Hz refresh rate to stabilise roll, pitch and yaw.
Reads orientation from an MPU6050 sensor and drives four motors from RF receiver channel inputs.
PID coefficients are set in the global variable section and can be tuned, with defaults for an F450-style frame.
Remote channel mapping can be changed in the configureChannelMapping function; mode 2 is the default.
Includes a start/stop safety sequence using the left stick of the remote.
Pure utility functions are extracted to src/utils.h and covered by host-side unit tests using PlatformIO and Unity.
