RE: JR9303 issue
While there may be a very remote chance you have a hardware problem, the overwhelming odds are that you have a programming situation. It is not serious enough to call it a problem! First let me expand on Rich’s comment, "It is better to use Mate, when possible, rather than using a Pmix." The reason for this is that the 9303 ACRO program mixes don’t carry the master channel attributes, such as trim, to the slave channels. This holds for all the flying surface channels. The Throttle channel is the only exception. When you are pairing ailerons, elevators, rudders, or flaps, use the Wing TYPE menu. With this menu when you select an optional wing type, enable the V-tail or dual/mate a channel, the master channel attributes will apply to the slave channel. No other way will do it.
Andy is most likely correct in diagnosing your problem. You have stated that you are using AUX1 for your second aileron channel. This is the default left aileron channel if you have chosen the flaperon wing type. I’m willing to bet this what you have done. If so, make certain your flap switch is in the middle position. If it is in either the upper or lower position and you haven’t reduced the FLAP SYS values, you will not be able to adjust the travel of either of the ailerons in one particular direction. This is because you have used up all the aileron travel in the direction the flaperons are pointing.
If you have dual ailerons and don’t wish to have flaperons, the correct programming is to use a NORMAL wing type and dual/mate an inhibited channel to the aileron. It is sloppy programming to use the flaperon wing type and then turn around and inhibit the flap channel to get rid of the flaperon function. You can get away with it on the 9303 and 12X but the newer 11X will not allow it.
