Tamiya 49498 F103RM Formula Car Kit - Race Tunable Chassis  [49498]

Track Focused Performance: Tamiya 49498 F103RM

The Tamiya 49498 F103RM brings a realistic formula racing layout to the model track, built around the proven F103 platform to give hobbyists an authentic handling feel. The kit captures the balance and sensitivity of single seater rigs at a manageable 1/10 scale.

Lightweight Drivetrain and Adjustable Gear Case

The F103RM chassis features components aimed at lowering rotating weight and improving response. The Formula Lightweight Diff Joint Set cuts rotational mass for crisper acceleration, and the Formula Height Adjustable Gear Case lets you alter clearance to suit different tyre profiles.

Suspension Designed for Controlled Handling

Handling benefits from a rear ball mount arrangement that replaces the older O-ring support, reducing vibration and creating a smoother roll. Up front the kingpin coil spring setup and a T-bar rear with a friction plate provide a predictable, responsive feel through corners.

Assembly Notes and Power Requirements

The kit includes a battery holder positioned to limit road contact and stabilise the car, plus an M-type body without markings. To complete the build you will need an R/C system, ESC, motor, a 7.2V battery and a charger so you can tailor electronics to your preferred driving style.

This Tamiya F103RM kit is suited to experienced builders who want a platform that responds well to setup changes. Its race-oriented parts make it a strong base for tuning and competitive club racing.
