RCU Forums - right stick not functioning

i have a 9zhp radio that was sent out to radio south for repair. this was done before i purchased the radio. i new know the person well who i bought it from and he also gave me the reciept for the repair work that was done.according to radio south the radio was gone through and all functions worked correctly after repairs where made.i honestly believe that this radio has been repaired correctly. i think the problem may be i have either accidently made this stick inactive or maybe could there be a mix that is making this stick disabled? i cleared the radio once i purchased it and i was wondering if maybe i disabled something or maybe the transmitter stick is just not set up correctly.i made sure it wasnt a reciver issue and checked it with other radios and it has worked flawlessly so i really dont think its the reciever.everything else seems to work fine on the radio but the right stick that being the aileron and elevator function.im trying to set this up for airplane use and i have made sure that the rx is in the correct mode for airplane use.the previous owner had used this radio to fly several heli models on it as well as a few airplanes also.
