The TRF 201 chassis has a stock maximum extended wheelbase of 10.5 inches and is too short to use in short-course truck racing. To combat this limitation of Tamiya not having a short course truck racing platform, I decided to manufacture my own chassis. Using 3mm carbon fiber stock I took a TRF201XMW with gear diff and extend the wheelbase. This car is used for drag racing and requires a 11.5 inch wheelbase. A wheelie drag bar was also added to the back of the car to prevent the front of the car lifting off and loosing steering control.
The chassis was manufactured on a Shapeoko 3 with 3mm carbon fiber. This CNC cut has features both on the top and bottom of the panel requiring a flip in the middle of the manufacturing process.
