Chassis kit TRF 421

This R/C model assembly kit creates a 2 belt driven 4WD, carbon fibre double-deck chassis.

New features - such as updated drivetrain, lower deck featuring new shape, updated (one-piece or two-piece) upper deck, front and rear A-shaped upper suspension arms, adjustable front and rear caster angles, and shorter dampers - will surely provide superior performance.

• 1/10 scale R/C chassis assembly kit.
• The drivetrain features the motor position moved 22.7mm toward the chassis centre compared to the TRF420X Chassis Kit (Item 42382) and has identical length front and rear drive belts for stable drivability.
• updated setup of spur gear and drive belts, only one dedicated nut is required to attach the spur gear, which enhances efficiency of maintenance.
• New lower deck is smaller compared to the one used on the TRF420X Chassis Kit to limit ground clearance when the chassis experiences roll.
• Choose from two types (one-piece and two-piece) of upper deck. Changing screw positions allows five setup patterns in total.
• A-shaped suspension arms are employed for higher rigidity. (The 420X chassis kit uses I-shaped suspension arms.) Longer lower arm spans limit swing width and ensure stability when the chassis experiences roll.
• Along with longer lower arm spans, front and rear suspension setups are changed from suspension blocks to suspension balls. Roughly 7mm-longer arm spans limit swing width and ensure stability when the chassis experiences roll.
• Toe angle can be adjusted by uprights. (Toe angle of lower arm inside is 0 degrees.)
• Three attachment damper positions (inner, middle and outer) on front and rear lower arms are offered by two types of aluminium bushings.
