While testing out the MotorCarrier board I was wondering why I'm unable to move a model craft servo with at least basically usable precision. It seemed like the servo jumps in steps of around 5°.

To find the reason, I digged into the source code and found this:

https://github.com/arduino-libraries/ArduinoMotorCarrier/blob/master/src/ServoMotor.cpp#L28

So the available range of 0° to 180° is broken down to a region of 7 to 28.

Why??? Why don't you communicate the 0° to 180° range directly to the firmware to make the servo motor outputs actually useful for more precise stuff?
