I noticed you have files for with or without rudder feedback. If rudder feedback is enabled in software but not needed, it can be connected to GND and it should disable it, so you could use the binary with rudder feedback. It depends on the hardware, but since my controllers (besides new high power version) use the 1v1 reference the rudder feedback gets divided and pulled down so if not connected it falls the GND. In other or custom hardware this may not be the case, so as you found, it's easy to disable by recompiling the motor controller sketch.
Also, you state that "normally the position sensors of the compass are factory calibrated" this is not quite accurate.
This true only for the accelerometer of the mpu9255, but it is not always true. Sometimes the mpu9255 accelerometer must be calibrated! This is maybe 20% of the sensors I received, and another 10% are actually defective, the rest don't need to calibrate the accelerometers.
The compass sensors always must be calibrated once mounted in the boat. This is pretty much true of any magnetic sensors.
