Vario Digger in Cat Yellow

[JDH429]

I think Ive got a handle on the wiring. Still need to make some minor connections and set the DIP switches on the 2x12. But the Dip on the 2x25 is set, red 5v wire is pulled back from the rx plug on the Roxy, Track , and swing motor leads are hooked up, Power from batt on/off is wired to both Sabertooths. It seems clear now whats going on here. considering looking into changing radios to a Dx9, or 10t...? Any input is appreciated.

Question for anyone, If running 4-5mm LEDs in series, Can they be powered and controlled by an open channel on the RX? Hook them up to the pos and neg, or pos and signal wire? Switching that channel on and off would operate the Lights? Thanks
