Product: 1:10 RC TRF421 Chassis Kit
The TRF series welcomes the brand new TRF421 chassis kit. This R/C model
assembly kit creates a 2 beltdriven 4WD, carbon fiber 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.

WARNING!
Read carefully and fully understand the instructions before commencing
assembly. A supervising adult should also read the instructions if a child assembles the model.
When assembling this kit, tools including knives are used. Extra care should be taken to avoid personal injury.
Read and follow the instructions supplied with paints and/or cement, if used (not included in kit).
Keep out of reach of small children. Children must not be allowed to put
any parts in their mouths, or pull vinyl bags over their heads.
Warning! Not suitable for children under 14 years.
Product details
- This is a 1/10 scale R/C chassis assembly kit.
- The drivetrain features the motor position moved 22.7mm toward the
chassis center compared to the TRF420X Chassis Kit (Item 42382) 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. (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 aluminum 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.

5° -2.5°
- Dampers are shorter by 5.5mm compared to the 420X chassis kit, which
provides a very low center of gravity and reduces the weight, for a more dynamic drive.
- Dedicated damper ends are used front and rear to ensure the same piston level.
- New damper oil seals (Item 51738) are used to keep the maximum oil amount and to make use of oil dampers efficiently.
- While the 420X chassis kit uses carbon fiber damper stays, this
chassis kit employs aluminum mounts for precise angle adjustments via the number of spacers used.
- Front and rear differential pullies are newly molded (planned) while
direct coupling and oil-filled gear differential are employed at front
and rear respectively. (The currently-sold Hop-Up Option and Spare Parts can be used.)
- Front features double cardan joint shafts while rear employs
lightweight universal drive shafts. New axle shafts (Item 42388) and
45mm drive shafts (Item 42387) are also used for both front and rear to ensure efficient drivetrain and maintenance.
- Newly-designed lightweight rear wheel axles enhance durability.
- Precision stabilizers are attached at a lower position than drive shafts for efficient maintenance of drivetrain.
Includes 1.0mm diameter (x1), 1.1mm diameter (x2) and 1.2mm diameter (x1).
- The steering system pairs dual steering arms and ackerman bush with a new steering bridge. Three types of
new spacers featuring different diameters allow steering angle adjustment.
- Includes Sealed Ball Bearings from the TRF series for efficient
rotation and Item 22078 Aluminum Differential Holders (0.8mm Offset, 2pcs.).
- Newly-molded quick-plate design battery holder does not require tape
for attachment. Depending on the battery pack equipped, change positions of spacers and posts.
- Comes with a carrying case dedicated for the TRF421 chassis kit.
- Please note that this chassis requires separately sold body, battery pack, motor, tires, wheels, and R/C equipment.
