This is a scratch built chassis I just completed for U13 Proxy race. The body is an ARII 1965 Toyota S800.
The chassis is combination of CNC cut brass, machined ABS plastic front axle mounts and my own Winpod for FF050 motors that I designed. I am not very good at soldering and bending brass....so I like to combine materials that simplify the process for me. I like to design in CAD, machine or 'grow' parts and then assemble them. The Winpod is available from Shapeways....just search for Brain's Bin or FF050 pod. Wheels are Slot Car Corner 14x6 insert wheels with Paul Gage tires. The wheel inserts are from the model kit...I had to turn them down a little to fit in the hubs.
