hmm I used a Flysky 6 channel radio when I did my tracked monstrosity that was made from HL tank parts with the throttle, and uhh right stick each controlling one side.
I started rebuilding my Tiger tank since I lost its controller with hobby grade electronics(reusing that controller), and would have finished if I didn't have some unexpected bills pop up(like the car I drove to works engine dying, and needing to buy another vehicle)
Dunno if you remember my tracked thing build


I scrapped it completely since as the things I was using for wheels shattered from the plastic being thinned out to get bearings in the bottom wheels
