These are the settings on my JR8310:
Exp: Aileron 70%, elevator 70%, rudder 50%
Elevator>Flap mix =125%, still experimenting for Elevator/Harrier
Rudder>Aileron +10% for right rudder, and +8% for left rudder
Rudder>elevator +8% for right rudder, and -10% for left rudder
SPOI>SPOI -100%, -100%: this is to get rid of any switches or pots on this channel, since it is my other elevator( reversed direction) channel
Elev>SPOI -89%, -104%. This should be -100%, -100%, but it is a mode 2 transmitter and I fly mode 1. It used to be the throttle channel!?!
These are the settings at the moment, but they may change as I trim the plane in some more. Hope this helped
