Tamiya 42139 - TRF511 1/10 Off-Road Competition Chassis Kit  [42139]

Precision Built for Off-Road Racing

The Tamiya 42139 - 1/10 RC TRF511 Chassis Kit represents the next step in tuned off-road platforms. Evolving from the TRF501X layout, this kit focuses on nimble handling and practical serviceability for experienced racers and committed hobbyists.

Lightweight Upgrades and Durable Components

Retaining the core architecture of the TRF501X, the TRF511 incorporates lighter elements and maintenance-minded details. Notable changes include reinforced drive belts that cut drivetrain play and reworked suspension arms that sharpen response, all derived from on-track validation to balance weight savings with durability.

Battery Position and Chassis Balance

The adjusted battery location improves front-to-rear balance to aid jumps and landings, while the split upper and lower center bulkheads make motor access easier and let you achieve precise gear mesh. Together these refinements produce a stable, responsive chassis for rough terrain.

The TRF511 is best suited to advanced RC enthusiasts who value a tunable platform and room for Grade-Up parts and setup adjustments.
