Here's the full scoop on this great new R/C buggy chassis from the Tamiya Website:

The TRF team has used their world championship knowledge to create the TRF201 to challenge the field in the very exciting R/C 2WD Buggy class. The TRF201 features a new chassis frame which has a longitudinal battery position with R/C units placed on either side for optimum balance and is designed to offer low center gravity and a plenty of ground clearance thanks to its skid-shaped underside. The motor is mounted at the rear to provide ample traction, and the new compact gearbox is equipped with a ball differential, ball thrust bearing, and traction control slipper clutch. Furthermore, the suspension is coupled with new long-span suspension arms and aeration dampers to enable superb control during high-speed off-road operation.
