Real Flight G3 multi mode. Trying to plug

[jim]

my JR xp6102 into the interlink controller and fly 2 models, eather split screen or not. I plugged into the DSC port and entered multimode on the sim. The model that the interlink control works, but the model I'm trying to control with the JR dosen't respond to inputs. It just rolls around uncontrolled until it crashes. I have tried turning the power on and off on the JR. I entered the trainer mode it,s onnormal and selected to FM.
Any suggestions???????????
