Tamiya 42103 TA05MS Tunable 1/10 Carbon Touring Chassis  [42103]

Introducing the Tamiya 42103 TA05MS - Tunable Double-Deck Chassis

The Tamiya 42103 TA05MS delivers a race-focused touring car platform with TRF-inspired enhancements. It is engineered to give hobbyists a stable baseline that responds well to detailed setup adjustments.

Double-Deck Carbon for Balance and Stiffness

The chassis features a 2mm upper and 2.5mm lower carbon deck that increases stiffness while keeping weight concentrated low in the car. This layout helps centralize components for consistent cornering behaviour and easier setup changes.

Efficient Belt Drive and Corner Control

Power is transmitted through a belt-driven 4WD system with wide pitch pulleys front and rear to improve drivetrain efficiency. A front one-way unit improves turn-in and acceleration control, while aluminium bulkheads add strength without excess mass.

Damper Options and Motor Cooling

3mm carbon damper stays give a variety of mounting positions for fine tuning damper geometry. The aluminium motor mount reduces weight and helps draw heat away from the motor during extended running.

Suitable for hobbyists who enjoy setup work and want a carbon chassis that responds predictably to tuning for different track conditions.
