The Tamiya 42183 - 1/10 RC TRF502X Chassis Kit provides a racing-minded foundation for off-road buggies. The shaft-driven 4WD layout and reinforced chassis elements create a stable base for adjustments and performance upgrades.
Core components include carbon fibre upper and lower decks plus aluminium and resin fittings that balance stiffness and weight. The motor is set in a front-mid location while separated battery areas at the rear help with balance and predictable handling in high-speed sections.
With suspension geometry inspired by the TRF511, the TRF502X employs double wishbones on all corners for repeatable wheel control. Large ball differentials front and rear, universal prop shafts, aeration dampers, and a spur gear slipper clutch round out a drivetrain that supports precise power delivery.
The kit includes carbon damper stays, aluminium suspension mounts, and full ball bearings to support a variety of upgrade paths. A clear body and wing are supplied, leaving tyre and electronics choices to the builder so the chassis can be set up for specific track surfaces.
The TRF502X is a strong option for modelers who enjoy dialing in balance and handling. Its race-derived parts make it a capable platform for progression in off-road competition.
