The number 1, 2, and 3 dials on my ar7200 spontaneously move when in flight. Vibration is not the problem. I was wondering if anyone else had this problem and how they solved it.

if it doesn't fit, make it fit.

Never heard of that happening to anyone but some scotch tape on top would probably work if you fly nitro use 3m tape or send it in good luck.

"spontaneously move when in flight. Vibration is not the problem."

What else could it be but vibes?.....

Could be just very small high freq. vibes....

Anyway, use some Windex and wipe the surface clean....

And put a small dab of silicon adhesive on them....

Even liquid electrical tape would work....

Easy to remove and re-apply when after making adjustments.

thanks for the suggestions.

As far as the vibs, yes I agree that the vibs interacting with this ar7200 are causing the dials to move, but the problems is specific to the ar7200 since substituting another ar7200 solves the problem.

if it doesn't fit, make it fit.

Wait; so you've already subbed in another ar7200 that isn't effected?

Sounds like you've already narrowed it down to just that ar7200 in particular!

So if I'm understanding this correctly I would send the effected ar7200 in to Spektrum for repair.

yes, it is a used unit. It is not under warranty and this seems like something I should be able to handle myself rather than sending it in.

if it doesn't fit, make it fit.

You can handle it.....

The pots are loose....high freq. vibes make them rotate.

Go to Home Depot and get some "liquid electrical tape" in your choice of color....and using a toothpick....apply a dab on the pot/case.

If/when an adjustment is needed, it's easily removed.....and then can be re-applied....

Contact horizon tech support.

Just because its out of warranty does not mean they wont repair and or replace, if not free, for a very reasonable price.

If anything, at least the phone call is free.

Phone calls sometimes works wonders....

But, I always wonder what kinda tech would work on it....don't want a rookie....

But, if they offer to replace the whole unit for cheap....I'd go for that....especially if you've bought a lot of stuff from them....customer relations and all that....
