About the TRF104

Chassis

The Tamiya TRF104 1/10 Electric 2WD Formula-1 Competition Chassis Kit is built for high-performance racing, featuring a premium carbon fiber lower deck that enhances both strength and lightweight agility. The chassis layout has been strategically designed to optimize weight distribution, with the battery pack, receiver, and servo positioned centrally to maintain stability and improve rear grip. The inclusion of a new steering arm design offers improved tuning possibilities with Ackermann adjustments, ensuring precise and responsive handling on the track. Additionally, the TRF104’s sleek and aerodynamic body design is complemented by a rear wing mount option that keeps the wing level even when the rear suspension moves, maximizing downforce for superior traction.

Drivetrain

At the heart of the TRF104’s drivetrain is a smooth ball differential system, which provides efficient power transfer and exceptional cornering stability. The rear differential unit is borrowed from the TRF103 chassis, utilizing a lightweight yet durable carbon fiber shaft that reduces rotational mass, making it well-suited for rubber tires. The motor mount features an innovative design that allows adjustments to both ground clearance and wheelbase, giving racers the flexibility to fine-tune their setup based on track conditions. Five different ground clearance settings in 0.8mm increments, along with two wheelbase options, ensure that the TRF104 remains adaptable and competitive across various racing surfaces.

Suspension

The TRF104 introduces a revolutionary suspension setup that eliminates traditional T-bars and suspension links, instead utilizing centrally mounted ball connectors on the motor plate to control chassis roll. This design enhances stability while allowing for precise tuning through roll dampers and adjustable roll springs located beneath the rear shaft. The front suspension features 2.5mm thick carbon fiber lower arms with two mounting positions for adjustable track width, while the redesigned upper A-arms—reminiscent of the TRF421—allow for easy camber adjustments. With plastic upper arms and an aluminum caster plate offering multiple caster angle settings, the front suspension delivers exceptional grip and responsiveness, making the TRF104 a formidable choice for Formula-1 RC racing enthusiasts.
