To make sure I understand this, the Traxxas Rally can be converted to the 4x4 with just the front and rear bumpers and body mounts? (In my case, I would be purchasing from scratch, so I'd need electronics and Tx/Rx, and will mostly bash with it, or visit a local club to race amateur from time to time.)
I would start with an ebay roller personally instead of buying the RTR, you can build a much better more durable Slash 4x4 for about the same price as the RTR's.
