I ordered the adjustable motor mounts to gear it down and the chassis stiffener center plate and will order some 9 tooth long pinion gears for my clod and juggernaut 2 soon. They are out of stock now. Still deciding on radio. I have a optic 6 or 3 channel radio. I have a 4 hitec lynx 4s channel but I'm saving my proton 4 for for my largescale. I could just us a axion 4 receiver?
