Default JR XP8103 programming question...

I have just bought my first airplane ever to have 2 servos for the elevator. I figured out most of the programming for it no problem. I made a mix to mix elevator to AUX3, and then I noticed that the 2 servos had very different center points. Then it dawned on me why this was. My aux3 potentiometer was maxed to one side. When I set the POT back to center (0) the servos now had the same center spot, travel and direction. Only when I touch the pot, the elevator half on the AUX3 channel moves with the POT. I can only set AUX3 to be on the AUX3 POT, the ELEV switch, the LAND switch, and I believe the PROG MIX switch. My other option is to mix the elevator to another channel besides AUX3, only the only un-used channel left is SPOI, and it has the same pitfalls.

My question is how do you guys get around all this?

Thanks in advance!

found this on another thread.

Dual Elevator Servo Set-Up

Now we will set up the elevators, so that we will have channels 3 and 7 working together. You will plug the right elevator into channel 3, and the left elevator into channel 7. Press the up key till you get to mix 5 or 6. We will use 5 or 6, as they are including mixes, meaning the elevator trim lever will operate both channels. If you do this mix on any other mix, the elevator trim will not work the second channel. Press the + key and change the first channel until it says elev. Press the channel key over to the second channel. Press the – key to change the second channel to SPOI. Make sure that beside SW: it says ON. If not, press the select key till the arrow points at SW, and press the + key to make this say ON. Press the select key till the arrow points at Rate: and make the percentage 100% by pressing the + key. Then move the elevator stick, and the arrow will move to the 0% in one direction of movement. Make this 100% also with the + key. Now we have the elevator working on both channels, but the aux 2 knob will operate the second channel. To eliminate this, will use another mix. For this mix, I would use mix 3. Press the DN key to get to this mix. Once at the mix, press the + key till it says SPOI for the first channel. Press the channel key so that the second channel is underlined. Press the + key and make the second channel is SPOI. Then press the select key till the arrow points at Rate. Press the – key till it says -100%. Then rotate the aux 2 knob, which is on the top left hand side. Rotate this until the points at the 0%. Press the – key till it says –100% also. This completes the set up of the elevators.
