Tamiya 42183 - TRF502X 1/10 Race Tuned 4WD Chassis Kit  [42183]

TRF502X: A Tunable Off-Road Chassis by Tamiya

The Tamiya 42183 - 1/10 RC TRF502X Chassis Kit is a purpose-built platform for serious off-road model racing. The shaft-driven 4WD arrangement and a selection of race-grade materials create a controllable base for tuning and setup work.

Chassis Design and Balance

The TRF502X features carbon fibre upper and lower decks combined with aluminium and resin fittings to achieve structural rigidity with targeted flex. The motor is placed in a front-mid position while battery packs are mounted rearward, a layout intended to aid stable handling under acceleration.

Handling and Drivetrain Features

Inspired by the TRF511 geometry, the kit uses double wishbone suspension all round to manage wheel travel and alignment. Large ball differentials at the front and rear, universal driveshafts, aeration dampers and an integrated slipper clutch in the spur gear provide a comprehensive drivetrain suited to tuning for different track conditions.

Buildability and Upgrades

The package includes carbon damper stays, aluminium suspension mounts and full ball bearings so builders can tailor the car to their needs. A clear body and wing are provided, and tyre and electronics choices remain flexible so the chassis can be adapted for specific surfaces or race classes.

For hobbyists focused on handling and precision, the TRF502X offers a solid starting point. Its race-oriented layout and component choices make it suitable for those wanting to push their off-road performance further.
