It looks like Target is only selling the complete packaged RC vehicle. The motor is a 550 type motor and the vehicle is weatherproof. It's pretty fast and the all wheel drive gives it nice power through grass. I don't think I'm ready for 50 MPH just yet, I'm still working on avoiding trees, small kids and mailboxes. Lol! Good thing this has big soft rubber tires. Lot of fun, but I definitely need more battery packs.
