Track-Focused TRF501X: The Tamiya 42105 World Edition

The Tamiya 42105 - 1/10 RC TRF501X World Championship Edition is a competition-grade assembly kit developed with Team TRF input. It emphasises predictable handling and resilience for hotly contested off-road events.

Construction and Race Intent

Offered as a build kit, the TRF501X is intended for modellers who enjoy precise assembly and setup. The package includes multiple option parts to refine on-track behaviour. A revised ball differential improves both feedback and longevity, while aluminium caster blocks and reinforced rear uprights strengthen the suspension mounting points.

Component Highlights and Drivetrain

Included features such as high-strength steel ball connectors and Delrin damper pistons help produce controlled suspension travel. The drivetrain employs an 18T centre pulley alongside a 37T ball diff pulley driving 369mm belts for consistent power distribution. The clear polycarbonate body is profiled to lower drag and enhance straight-line stability.

The Tamiya 42105 TRF501X World Championship Edition is suited to club competitors and skilled hobbyists seeking a durable chassis ready for frequent tuning. Its race-oriented design supports progressive upgrades and track testing.
