Tamiya TRF104 Chassis Kit

The Tamiya TRF104 Chassis Kit is a 1/10 scale 2WD RC car kit. It arrives as a box of parts rather than a finished car, so you assemble the chassis, fit the electronics and paint or trim the body before the first run.

Finished, it measures 325mm long.

Tamiya supply an electronic speed controller in the box.

• Camber angle is adjustable freely from +1 to -3 degrees (approximate) using a 2mm hex wrench
