Go to Trackside and get one off the shelf or go to Hobby Town by the Culver's in West Allis and pick one off the shelf from them.

Slash 2wd - $240 RTR and it has everything you need.
Losi XXX-SCT 2wd- $229 RTR (if i wasn't wanting to race the spec slash class I would buy this truck)

Slash 4x4 - $349 RTR


Want the better LiPo batteries, they are about 60-100 average depending on a couple variables, and then pick up one of the chargers that does lipo. Mine was $120 with build in balancing for the batteries. Venom makes one and I believe it's $150.

Then just go outside and have fun.
