Help With Radio Set Up Problem

Need some guidence here please. I have a JR10X Airplane version transmitter. I am trying to setup a foamy 3D plane in it but the ailerons are acting like there is differential is set up but it isn't. I am using the "flaperon" setup with split servos for each aileron. One servo is plugged into the "aileron channel" on the receiver and the other one is in the "Aux. 1" channel. With the travel adjustments set at 100% for each servo in both directions and the servo sub trim set at "0" for each channel. The differential setting for each channel is set at "0" but when I go "full" aileron...one servo will travel full left and the other one about half that distance and when I go "full" aileron the other direction the travel does the same thing...one servo goes full travel and the other one only about half travel. Any ideas? Thanks, Don....

I am not familure with the radio, But the way it is operating seems to be the prefured way to have them operate.. It might be a built in feature of the radio. But I am just guess in there.

Hopefully a 10X guy will jump in here. In the meantime, it sounds like you might have flaperons deployed. Flap knob? Switch? Are the half travel both downs?

Flaps are at even. Travel is equal. Ken-Ohki, are you saying most pilots are using this "differential" type set up where one aileron moves say 50 degrees and the other only 25 degrees? Thanks..

Yeah, pretty much,. the control surface that is raised should be more then the one that is down, some say 50% some say 25% less some say whatever works best for them, But most will agree they should not move equaly.

Is more down aileron than up aileron peculiar to a 3D plane?

I always thought aileron differential was more up aileron than down aileron.

Bill, I thought the same thing. If you give it right aileron then the left aileron didn't have as much movement as the right. Whenever I have used differential it has never been so extreme as this. I guess I will just have to give it a try this way and see how it goes..Thanks guys.....Don

Yes, the traditional use of aileron differential is to compensate for adverse yaw and the more down than up will just contribute to more adverse yaw.

As I implied, I don't know the 10x, but have programmed other JRs and never run into a default aileron arrangement that you describe.

I have managed to screw up by setting servo travel properly, zeroing trims, but forgot to check flap settings. Then rigged the aileron control rods assuming the servos were at neutral when, in fact, they were set for some degree of flaperon deployment.

Try the Code 75 Servo Monitor function. Are the servo travel indications uneven on the display? Maybe it's just the way your servo linkage is set up.

Miami Mike,
When I check the "servo Monitor" the elevator and the rudder are right in the middle of each of their graphs but the right aileron and the Aux. 1 and close to each end of their graphs but...well here...I wrote this out and to show everything I have done so I will just copy and paste it below..Maybe someone can set me straight..

I know that there are JR 10X radio experts on here so here goes... I have the JR 10X Airplane version (well actually I have both the airplane and heli but only having trouble with the airplane version at this time) and I am using the "flapperon" wing set up but I have opposite aileron differential going. When I give it full right aileron the right aileron goes about half way up and the left aileron goes full travel down and visa versa when applying full left aileron. I tried the "turn" icon on the wing style page and nothing changes. I have the sub trim on the "aileron" channel set at "0" and the Aux. 1 channel set at zero and the 100% travel on both channels and the servo arms are at 90* with the servo case. I am trying to set up a 3D Foamy type plane with split aileron servos and have A LOT of control surface movement so it is very easy to see that I am not getting nearly as much travel one way as the other. When I view the "Servo Monitor" on the 10X I see that the elevator and rudder are in the middle of the vertical graph but the right aileron and the flap (Aux.1) are way up and way down on each of their graphs and nothing I have tried is working. Nothing changes. I know that sometimes it is a very simple to correct these problems if you just knew what to do. At this point I have tried everything I know of.. Any ideas?
Thanks in advance for any help I get.....Don

Well, I found the problem. The slide switch on the side of the 10X even though it was all the way up (no flaps setting) it was causing the problem. I de-activated the switch and that took care of the problem.....Thanks....Don
