Tamiya 18613 TRF-Racer Jr. Quick Look

The Tamiya 18613 TRF-Racer Jr. brings race car styling into a compact Mini 4WD format, aimed at hobbyists who enjoy hands-on tuning. Its aerodynamic shell and modular chassis make it a versatile platform for upgrades.

Visuals and Shell Features

Featuring a lightweight polycarbonate body, the car benefits from good impact resistance and low mass to help top speed. The unpainted shell invites personal paint schemes using polycarbonate paint for a customised appearance.

MS Chassis Engineering

The MS chassis uses a detachable three-piece layout to simplify setup changes and repairs. With a mid-ship mount and double shaft motor, power balance is improved, which supports confident cornering and steady straightline speed.

Upgrade and Tuning Choices

• Motor Choices: Compatible with several double shaft motors to suit sprint or endurance style running.
• Wheel Options: Small diameter wheels are standard, with alternative rims and tyres for varied grip.
• Gearing: Supplied at 3.5:1 but can be adjusted to tailor acceleration or top speed.
• Chassis Mods: Removable sections allow for experimenting with balance and ride height.

Suitability for Different Tracks

Battery placement beside the motor lowers the centre of gravity and helps keep the model stable through tighter turns and on fast straights. The TRF-Racer Jr. suits racers who want a base chassis they can adapt for different track demands.

The Tamiya 18613 TRF-Racer Jr. is a practical choice for model racers seeking a tunable, race-styled Mini 4WD that responds well to upgrades.
