I bought a roller for a little over 100.00, then spent about another 100.00 to get her on the track. What helped was the HK 120A ESC and i already had a 5700KV mamba already so all i needed was a servo and used my tires off my 4x4 slash. I plan on painting the JConcepts body and get her on the track again...
post some pics when you get the stuff you need..
