After that it started oscillating madly after it binds to the Tx. It sits there with that one aileron going madly up and down through 10 degrees or so and all other controls neutral. When I move the ailerons, it calms down and seems normal.
Be careful. My ailerons went "crazy" during flight. Fortunately I put her down in the tall weeds. No damage.

Here is a video of my airplane misbehaving...

I've been on the phone with HH and they are sending me a new aileron servo. However, as an experiment, I replaced the "bad" servo with a servo from my Parkzone Mustang. The problem remains. So, it may be a bad receiver.

Is anyone else seeing the same issue as in the video?

Thanks, JJ

I am thinking if you are on a "Y" connector it should affect both servos......if it is the Rx

Was the servo you substituted a digital or analog? Those servos should be on a "Y" cable. Did you change any of the connections? If the servos are on a "Y" cable both servos would be acting up if the receiver was defective.

This is true. It's been a long process of troubleshooting. I'll report back after I get the new servo from HH.

I checked and rechecked all connections. Also replaced the y-harness. As for the digital/analog question, I am not sure. Update later.

Thanks, JJ

Remove the servo arm off the original servo that came with the plane and then power up the plane to make sure you are not binding. If it is still dancing and the other servo is fine you will need to replace.

What happens when you move the aileron stick?? Does it quit jumping around and does the other servo work properly?? Just wondering because I have one aileron jumping like that but the other aileron servo doesn't work at all. This all happened after the elevator clevis sheared and the plane hit the ground. Horizon sent me two new servos out today.. One to replace the twitching one and one to replace the one not working.. The HH Tech Guy said it would be safer to just replace both and not take a chance just in case one had a short in it..and of course at no charge.. I just hope the new servos don't do the same thing..

Any chance you damaged the servo wire when pulling wire into fuse? Plug any old servo into the female Y just to see if it jitters. If so, not the servo. If not, then servo or servo wire.

The parkzone servos have long had issues and they finally came out with some new ones and already numerous reports of problems. Not good. Dont know why they cant seem to make good servos. ?

Please, for the love of all that is not corporate and unholy, sell me an airframe in a separate package at an ARF price. I wish more people would demand this from them.

After binding, the left aileron jumps around. If I move the stick, the left aileron continues jumping around, and the right aileron does *not* move at all. Yes same symptom.

I tried several old servos and yes they all jitter. Also replaced the y-harness twice. That's why I think the problem is *not* the servo.

Thanks for the input guys. Hopefully we'll get this worked out.

Did you try pluging servo directly into ail channel (remove the Y). Currently it defies logic why one servo would swing and other does not as they both getting same signal. Unless the *other servo is broke and the one you think is bad is good.
