*** EDIT: Problem has returned, it's glitching off and on, without any discernible pattern ***

Mostly recording this for posterity, in case someone else encounters the same problem. Hopefully this will benefit you in some way.

If anyone has any experience with a similar problem, with this radio or another brand, please feel free to chime in

I went out to the field to fly tonight and I was doing my preflight checks when my ailerons started moving erratically, sometimes fully extending on their own, they'd stay extended for a while and would then return to neutral eventually. Then they'd twitch and jitter some more, I still had some measure of control, the ailerons still responded to my input (most of the time, until they got a mind of their own again).

After unplugging the servo y-harness from the receiver and plugging it back in and unplugging the battery and plugging it back in (you never know, right?) it seemed to get a little better (the movement became less pronounced). The ailerons where still not responding to my control input normally.

So I packed up my stuff and went back home

I wanted to determine whether it was my TX or something with the wiring in my plane, so back home I plugged my USB simulator cable into the tx and went to the calibration screen on my favorite sim. When I moved the ailerons it was obviously jerky and would "jump" sometimes, even though I was moving the stick smoothly.

After playing around with it for a while and moving the rudder, throttle, etc. (which all moved normally) I finally decided I would center the trim dials, for no particular reason. All of a sudden the glitch was gone, and I could not reproduce it by moving the trim back to where it was previously.

By this time it had gotten dark so I haven't had time to take it back out to the field to do rigorous testing, but I'm hoping to be able to postpone the inevitable upgrade to a 'real' radio for a little bit longer...

Hope this helps someone else down the line.

Little bit of advise if theirs radio towers near you i wouldn't use a 72mhz radio because you will get interference witch may cause a crash like mine which broke the cheap dynam receiver.
Landing is just a controlled crash:yes:.

Seems like my success was short-lived. Radio is back to glitching off and on unpredictably...

I've been flying on the simulator and it was glitching again and now it's stopped again - I wish it would just glitch all the time or not at all, not crazy about trying to fly my plane like this

Well the only Dynam TX i had was from my hawk sky and it was bad from the factory when i turned it on it started smoking.But know i have a dx6i and im loving it.Seems that bad TXs might be a common thing with Dynam but you get what you pay for.

Is it possible that two serves places too close together might cause glitching?

They're both in their own wing, so I don't think it's that - besides, it's doing it in my flight sim as well, ruling out a problem with the plane.
But like ImGonnaCrash said, you get what you pay for, it looks like there's something wrong with the pot meter (I think that's the preferred nomenclature?) that operates the ailerons.

What plane did you buy Hawk Sky?

Yeah, it's a Hawk Sky

please try out the following:
Plug the ailerons into your rudder channel and the rudder into the ailerons channel
if the rudder then moves irratically you can rule out the servos.
Next plug in nothing but the rudder into the ailerons channel (and the ESC of course)
If the problem still occurs it's not the cables either.
Then if the problem still occurs and the ailerons are just moving around, switch of your transmitter. If the servos keep glitching, it's not the TX (at least not alone) but also the receiver. If the servos stop instantly and do not move any more I would say your transmitter has a problem.

Though the fact that you have the problems too with the sim already suggests it's a transmitter problem I think you should really try and prove that. Not that you order a new transmitter only to find out you had some broken cable or something like that.

It sounds like you are having a problem with the trim pots for the ailerons. You may be able to clean them with contact cleaner

Thanks DJRubberCow, excellent tip - I'll try that later today!

dfarmercse - I was thinking the same thing, I'm going to try the instructions DJRubberCow wrote up and unless that reveals anything different I'm probably going to have to take stuff apart and try to clean it, ugh!

Thanks guys, the advice is appreciated!
