1/10 SCALE R/C TRF421X CHASSIS KIT

Length: 397mm. Image shows assembled kit.
*Swing shaft cap ball bearings give smooth efficiency.
*Body, R/C equipment, motor, tires, wheels, battery pack and charger sold separately.

This R/C model assembly kit creates the 2 belt-driven 4WD TRF421X, the latest model in the line of TRF chassis; it has been tuned based upon racing feedback, and offers superior drivability and cornering performance. Its double deck layout is composed of a 2mm thick aluminum lower deck and carbon fiber upper deck. With a new motor mount, the kit enjoys a lower center of gravity and optimized flex. Fine-tuning of suspension material gives stability in high temperatures or on high grip surfaces, in conjunction with 1.2mm and 1.3mm stabilizer bars. New knuckle arms’ front Ackerman position gives more direct steering, while the hole on the rear arms moves adjuster rod attachment positions backward for optimum grip on low traction surfaces. Drive shafts have swing shaft caps with ball bearings to limit friction and speed loss.

A close-up look at the steering setup. Use spacers in the linkage to change its range of motion.
Carbon fiber-reinforced arms are paired with a new Ackerman position for the knuckle arms that gives more direct steering.
High-performance TRF dampers can be fine-tuned to your requirements. Aluminum damper stays are new.
Front drive shafts are double cardan and have ball bearings in the shaft cap for efficient drive.

The 2mm aluminum lower deck is designed for optimum flex and weight distribution. The motor is lower.
A new motor mount gives more precise assembly. The motor is 1.0mm lower than on the TRF421.
A closer look at the easy access spur holder. The spur gear nut limits gear wobble.
1- and 2-piece upper decks are included.

Choose between flanged screw or flanged pipe and dedicated screw attachment methods.
Lightweight rear universal shafts use ball bearings in the shaft caps.
Rear arms are the same carbon fiber reinforced design as the front. Use spacer to fine-tune roll center and caster angle.
Precision stabilizers can be used with high traction tires. A choice of 1.2mm and 1.3mm options is included.

The 30g battery weight helps balance your chassis. A 20g receiver weight is also included.
3.0mm carbon fiber mount stays are paired with 2-part mounts. Choose upright or horizontal position.
A sticker sheet is also included.
