PX4 config: Insist on correct throttle position before accepting RC config end
Leave out confusing technical detail. Just tell the user we’re done.
PX4 config: Cleanup in RC value handling.
Use the reversed values for the four control channels as well. Not using them would make the display very confusing.
PX4 config: Remove the specialized throttle handling - this needs testing, but doing the math on paper it doesn’t look like a special case is needed / wanted here.
