Redefining Precision: The Tamiya TRF420 Chassis Kit
The Tamiya TRF420 chassis kit represents a significant evolution in the world of 1/10 scale touring cars. Following the successful lineage of the TRF419 series, this new model incorporates cutting-edge features that cater to both seasoned racers and those new to competitive RC racing. With a focus on precision engineering and adaptability, the TRF420 is designed to push the boundaries of performance on the track.
Innovative Engineering for Enhanced Performance
At the heart of the TRF420 is its meticulously engineered 4WD belt-driven drivetrain, which includes a rear gear differential and front/center direct pulley system. This setup not only ensures smooth power delivery but also allows for precise handling adjustments. The newly designed gear diff pulley and case parts reduce weight by 1.5g, minimizing oil leakage and enhancing reliability.
The TRF420 also introduces an integrated plastic part for the front direct pulley, saving an additional 2g compared to previous models. This innovative design allows for easy replacement of direct cups without disassembling the entire pulley component, streamlining maintenance and setup changes.
Advanced Suspension and Steering Adjustments
A standout feature of the TRF420 is its adjustable suspension system. The new suspension arms utilize bushing inserts, offering customizable lever ratios for varied track conditions. The rear arms are offset by 3mm, improving traction by allowing a shorter lower deck. Adjustable suspension mounts and bushing designs provide a wide range of toe, roll center, and caster angle settings, giving racers unparalleled control over their setup.
The updated steering linkage pairs with a new steering pivot component, facilitating quick and easy tweaks to the steering configuration. This level of adjustability ensures that the TRF420 can be finely tuned to meet the demands of any competitive environment.
Lightweight Components for Optimal Balance
Weight reduction is a key focus in the TRF420's design. New lightweight wheel axles are approximately 1.5g lighter than previous versions, and the durable stainless steel suspension shafts, now 3mm in diameter, enhance the suspension's sturdiness. These components contribute to the overall balance and responsiveness of the chassis, making it a formidable competitor on the track.
