Let's see if I can do this without it being classified as support for non-Traxxas stuff.....
Bought myself the Spektrum DX4S for my birthday last week with with the intent of using the 4ch receiver with my Summit and I picked up a new waterproof 2ch for my Slash.
My Summit is still running the Traxxas ESC but with dual Dewalt 14.4's as well as a single high torque steering servo which freed up the second "1" servo ch for my LED lightbar. I split the current stock lighting wires to also run fans for each motor.
The Summit receiver is labeled 1,1,2,3,4 and batt/5
The "other" receiver is labeled BND, str, thr, aux1, aux2
I guess my question is can a Summit use a standard 4ch receiver (and can the bind ch be use to power lights and/or the third Summit servo)
