On mine I have:

throttle
aileron
elevator
rudder
gear (governor on/off)
pitch
aux2 (gyro gain)
aux3 (head speed switch for gov)
aux 4 ( battery checker)
Bat (battery)

I can't get back into my receiver cos it's wrapped in foam and securely tie-wrapped so these were just from the top of my head. They are probably in the wrong order or have some mixed up.
