Dean,
Easy fix. There is a steel pin that can work its way out and starts rubbing on the side of the stick assembly. It is what the plastic levers that have the springs on the ends of them ride on. Push the pin back in a little with a small flat bladed screw driver, and use a dab of thick CA to hold it in place. Hit it with some accelerator, and you are done.
Stiffer springs have not been an issue on JR's that I know of, if properly installed. Tony has some tricks to make sure they don't break the tabs. The steel pin issue seems to be the only weakness in the 9303, and is common with the 10x. The 12x seems to have fixed the issue with the new assemblies.
I like my 12x a lot. The new Airtronics looks interesting, but it only came out a couple of days ago, so user experience is limited. It is going to be interesting to see how JR and Futaba react to the new Airtronics and Hitec systems that are considerably less expensive.

I am having a JR 9303 TX issue myself. My right hand stick is sticky and crunchy when I hold full right aileron and bump up and down elevator. Just noticed it today on my 5th practice flight. I also seem to be getting little bumps of left aileron roll when I was flying straight and level. Really weird and not cool at all.
It might be time for me to break the bank and do a major upgrade. 12x or 14mz would be nice, now I only have to rob a bank
It will be on the way tohorizontomorrow. Since I am not running any mixes I may just run my el cheapo JR 6102 until I get it back.....
It's alwayssomething
