I just picked up a used dx5 pro transmitter and bound it to my 4x4 sc and its twitching. I previously had my dx6 rugged bound to it with no issues. My sc truck and all electronics are brand new. The steering and esc are both glitchy and twitchy acting. I bound my dx6 rugged back to it and its fine again. Any ideas?

These numbers are constantly moving between 0 and 3. The same glitchy movement as the steering and esc have. On my dx6 rugged the numbers are on zero and not flickering.

If you can see it on your display then it is within the transmitter and it sounds like a dirty potmeter. So you bought a used transmitter?
If it is new, go back to the shop, if it is used you need to open the transmitter and spray some contact spray into the potmeter or the best solution is to replace the potmeter.

thank you for the response. Yes i bought it used. The guy is being great about it and will be refunding me if I can't get it working properly.
