Mine is a used C-16 that has been set up for battery power using an AirWire G3 board and an AirWire T5000 controller. I have only been running it for a few weeks. Early on it would stop going forward just occasionally. If I would then turn the forward command back down and reverse the direction of the locomotive just for a second or two and then stop and change to the forward direction, then it would immediately run fine for quite a while. Over these weeks, the inadvertent stops have increased in frequency until now when it can happen every foot or so. Would anyone out there know if this is likely caused by a communication breakdown between the controller and the locomotive or strictly a mechanical issue within the locomotive? Thanks for any help on this. Jim

Sounds like this is going to be hard to answer over a forum.  It sounds like either something mechanical or some issue with the Airwire electronics.

Got it going, but don't know what fixed it.
