I converted my Bachmann rail truck to battery and RC. I used a Rx65 receiver mounted under the seat in the cab. I shortened the coffin box and mounted it sideways for the battery. The battery is a Turnigy 2s Lipo (7.4v) 850 mAh. I origanally planned on using a 3s Lipo (11.1v) 1300 mAh battery but the one I ordered was two tight of a fit. I like the speed it provides. I’m hoping to have enough room for a Phoenix P8 in the coffin box and my plan is to mount a speaker on the bottom of the cab roof facing down.

Good luck trying to fit all that stuff in there.

I built a van body to house the stuff in.

trying to remember how I had mine done…I did the Elsma under the cab roof, something under the seat and built a ‘cargo box’ to house battery and switch…also did the resistor thing for the lights…pics are somewhere?

How about this for a small combination 2.4 GHz RX/ESC.:

3 amps up to 18 volts. 2 x sound triggers and F & R LED lighting outputs.
