I would like to add that I recently purchased the Hyperdrive 12th scale car and I love it. It's based on the 12L3 but has some really nice upgrades including the large D-ring IRS type diff. Nashracer and Tempest2000 will verify that even though it didn't have much of a driver, the car was really good the first time it touched the track. In fact, I finished building it and setting the tweak as they called for the first round of qualifying!!! LOL
