Tamiya 1/10 TRF 421X Chassis Unassembled RC Kit

Developed for serious competition use, the Tamiya RC 1/10 TRF421X Chassis Kit takes the TRF421 platform to an even more specialised level. Its updated two-belt 4WD architecture combines a lower aluminium motor position, a 2.0mm aluminium lower chassis deck, revised upper decks and carbon-reinforced suspension components to produce a low, rigid and highly tuneable platform for high-traction racing surfaces.

Please note this is an unassembled kit requiring assembly; it ships as a build-it-yourself kit and does not arrive pre-built or ready to run.

Special Features:

• Scale: 1/10
• Plastic model kit [unassembled]
• High-performance 4WD touring car assembly kit
• Two-belt driven 4WD drivetrain designed for high-traction track conditions
• Aluminium motor mount positions the motor 1.04mm lower than the standard TRF421 for a lower centre of gravity
• 2.0mm thick aluminium lower chassis deck provides a precise balance of chassis flexibility, rigidity and weight distribution
• One-piece and two-piece upper deck configurations allow different chassis-flex characteristics
• Carbon-reinforced nylon upper and lower suspension arms provide controlled flexibility for demanding track conditions
• New front and rear damper stays move damper attachment positions 1.0mm inward
• Precision stabilisers include 1.2mm and 1.3mm options for different track surfaces and driving styles
• 20g receiver weight and 30g battery weight help optimise overall chassis balance
• Oil-filled rear gear differential and direct-coupler front drivetrain provide competition-focused power delivery
• Full ball bearings, adjustable suspension and aluminium TRF dampers are included
• Designed to be compatible with selected standard TRF421 components and setup parts
• Dimensions [cm]: 39.7 long (without body) x 18.7 wide x 25.7 wheelbase
