Tamiya’s TRF R/C designers never rest. They are constantly looking to bring our most hardcore R/C racing fans the absolute best features able to be squeezed into a 1/10 scale touring car chassis! After two and a half years of development, we now bring you the ALL-NEW TRF 421. The highest end touring car chassis series we produce has received a whole new suspension and layout makeover!
New features:
This 2-belt driven 4WD carbon fiber double-deck design is loaded with new features such as an updated drivetrain, a new lower deck shape, front and rear upper A arms, and new shorter dampers, all of which promise to translate into serious speed on the track! Other notable features include a choice between one- and two-piece upper deck layouts for different chassis flex characteristics, plus updated suspension geometry that keeps the chassis more stable.
Key Features:
The Drivetrain uses a front direct coupling and rear oil-filled gear diff. Equal length front and rear drive belts minimize pitch.
Suspension Arms are a rigid "A" design with 7mm longer span compared to the TRF420X for stable roll, while upper arm mounts can be slid to adjust camber.
Three damper pivot positions are provided.
Dampers are 5.5mm shorter than on the TRF420X, for a lighter chassis and lower center of gravity. Attach them directly to aluminum mounts and fine-tune with spacers.
