I could go with the tri pact speed control, but then I would need the turret transverse for precision aiming, which I do not know how to do. I also still haven't fully decided yet on what marker I want to use, and how to control it. I also have to decide on the track and suspension system.I am definitively going to use a Cheap Control System.
I'm thinking for a track take a notch vbelt and have the track pads attached to it on the outside. I will have the pullies inbetween 2 wheels for all the drive and idler and road wheels. That way, the belt is what is powered, the pads provide traction, and the wheels are for looks and help with little objects forcing up on the pads. What does any1 think?
