Default Spektrum AR636A Rx help

I discovered a problem today when I went to fly my ParkZone T-28 with the AS3X AR636A Rx. The rudder will only travel about half way. It appears to be a problem with the Rx. If I plug the rudder servo into the aileron plug on the Rx, it travels all the way. If I plug the aileron servo into the Rudder slot, it only travels half way.. So to problem seems to be the rudder output from the Rx.

How can I correct the problem?

Possibly Rudder Dual Rate is activated in your transmitter and is currently in low rate.

Worth checking.

Yea, I checked all my setting and everything is OK. I even hooked the rudder servo to another Rx and it worked normal, dual rate and all. The Rx is a programmable one and I think something in the program got changed somehow. I don`t program it .. I just use it as it came..

I might wonder if you need to calibrate the sticks on your transmitter.

It is not the transmitter.. it is a receiver problem.. works perfect when the Tx is bound to a different Rx.
