Tamiya 49401 TRF501X High-Performance 1/10 Electric Buggy Kit  [49401]

Development Story Behind the TRF501X

Unveiled at a major hobby expo, the TRF501X blends TA05 platform experience with a front/mid motor layout and a twin-belt 4WD system. Its 2.5mm carbon fiber upper and lower decks deliver a rigid but responsive base, ideal for technical off-road circuits and club racing.

Engineered for Handling and Speed

Attention to chassis geometry and suspension tuneability gives the TRF501X its edge. The 4-wheel double wishbone setup offers a wide tuning window, while aeration type oil dampers help maintain traction and control through jumps and rough sections. Early competition placings highlight the kit's race-oriented potential.

Construction Details and Setup Notes

The kit includes both front and rear ball differentials to improve balance and stability during fast transitions. The aerodynamic bodyshell and rear wing work together to improve landing stability, and the layout accepts saddle pack batteries. A belt guide roller is fitted to reduce belt slip and improve drivetrain efficiency.

For experienced builders and racers who prioritise handling and tunability, the TRF501X provides a competitive platform that responds well to setup changes and performance upgrades.
