I have taken a punt and gone for the Train Engineer revolution DCC system for battery R/C of DCC equipped locos. It comes with a 5A mobile booster receiver which has easily fitted inside my Bachmann C-19 including batteries. I haven't had the chance to try it yet as I'm waiting for a plug and play Zimo with the C-19 file added to arrive.
To be honest, the instruction manual isn't particularly user friendly, but i was swayed by the handset's F0-F28 capability. I had almost bought another system by Fosworks which is excellent, but I think it could only manage 12 functions, which would have limited the functionality of my decoders.
If anyone has set up their loco for this system, I could appreciate some instruction in layman's terms please.
