Bud:

I had the same problem with mine, besides the left gimbal screwed-up from the factory. The jack is on a long, narrow circuit board on a self-aligning mount, that, well, doesn't self-align. Mine wasn't seated into one of the posts internally. If yours is seated, you may have to manipulate the board/jack assembly internally to correct it. It is the worst mounting arrangement I've ever seen. My left gimbal saddle wasn't fully snapped into place either, which skewed the stick, and caused the centering pin to jump out of its alignment hole.

I don't know if it will void your warranty if you open the cover to check, I did mine, I'm an electronics engineer, and I sure as he** wasn't going to send it back and wait weeks for them to send a new one, and not able to use G3 with another USB interface and my transmitter, because it is a serial numbered, registered controller. A ridiculous software/hardware monopoly, that does nothing but inconvenience loyal customers if they experience trouble with the interlink controller. Bad business, pure and simple.

Good luck!
