About this product

The Tamiya TRF421 Chassis Kit is a 1/10 scale 4WD RC car kit. It arrives as a box of parts rather than a finished car, so you assemble the chassis, fit the electronics and paint or trim the body before the first run.

Tamiya supply a 540 motor and an electronic speed controller in the box.

Key specifications

  • 1/10 scale RC chassis assembly kit
  • The drivetrain features the motor position moved 22.7mm toward the chassis centre compared to the TRF420X Chassis Kit and has identical length front and rear drive belts for stable drivability
  • With updated setup of spur gear and drive belts, only one dedicated nut is required to attach spur gear, which enhances efficiency of maintenance
  • The 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. (The 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
  • Changing positions of upper arm mounts by screws allows changes to front and rear caster angles, which is suitable for current high-downforce races. Front caster available angles: 3, 4, and 5 degrees. Rear caster available angles: -.5, -1.5, and -2.5 degrees

Tamiya kits are designed to be built with hand tools and a clear manual, which is what makes them a common first build as well as a shelf favourite.
