[quote]QUOTE: Originally posted by dblount Sorry bout that, this is all plug and play and a little soldering of course. ESC - Electronic Speed Control (www.astroflight.com in this case) BEC - Battery Eliminating Circuitry, in the R/C car racing world we dont want to run around with the extra weight of the 4-AA Cell battery pack running the reciever and servo. In the R/C Plane world, they dont want to loose radio power when the 'main' motor batteries run out for obvious reasons. Like I said above, unfortunatly this ESC does not include BEC, so you can either run the 4-AA cell pack that comes with the radio or just build a simple 5V regulator circuit that steps the batteries ~18V down to 5V. (this is exactly what I run, http://www.hut.fi/Misc/Electronics/circuits/psu_5v.html) (~$5 in parts) For reversing we run a ON-OFF-ON DPDT Switch between the esc and motor. Make SURE to use a fuse (3 to 4 Amp seems to work well) between the ESC and the Locomotives motor, yes I have rewired entire locomotives. Also, the Locomotive must be rewired with at least a switch so that the power from the batteries is not backfed into the rails. Most of our engines have been converted to strictly battery, so I just take one set of the brushed (in most cases) from one side of the engine out and save them if at some point someone wanted the engine to go back to track power. If there is interest in a schematic, I could draw something up... let me know. [/quote]
