The RCS Tx-3 has three pushbuttons. Ch # 5 plus one that operates the bottom half of the Ch # 2 servo movement (F1). The other operates the bottom half of Ch # 4 (F2).
The internal Deltang TX2 module is using profile # 5 which does permit no internal wiring connections on Ch # 2 and Ch # 4. (TX-1).
I would suggest you get in touch with Andy Rutter at Micron R/C in the UK for help. He is very knowledgeable. http://www.micronradiocontrol.co.uk/

in this case ch 2 and 4 are preset as digital channels and it is quite easy to replace the two push buttons with simple toggle switches. These keep their switched position and you can use pad3 and pad4 then for switching marker lamps and number boards on/off, without programming of the Rx.
Otherwise you could reprogram the Rx65 pad 3 and 4 to latching action and keep the push buttons. Not as half difficult as you may expect.

Took me about 45 minutes to wire it up this evening, other than having to open it back up to tape down the wires to the headlight ( rubbing on the front flywheel), everything worked first time. Oh, I did have to reprogram the Rx to get the Tx to respond from full counterclockwise (stopped) to full clockwise (full throttle), the Rx came setup for midway of the throttle to be stopped/idle. Reprogramming took just a couple of minutes.This is my first diesel converted to BPRC using the Deltang 3amp Rx board. I had to solder only 3 or 4 wire connections and tin a few more, the BIK has screw terminals which made most of the wiring a piece of cake. I left the original motor wires in place, simply hooked them up to the Rx (actually got the polarity of the motors right the first go!).Fine slow speed and adequate top speed, I'll have to run a test to see what the top end is.Again, no sound or smoke, but there's enough sound from the rails to let you know it's moving.I left the markers unlighted, as of now the numberboards are also unlighted. The decals are clear enough they may not need LEDs, but if they do I can put them in later.Hopefully I can make a crappy video of it for a little show and tell.
