Overview of the Tamiya 18613 TRF-Racer Jr.

The Tamiya 18613 TRF-Racer Jr. is designed for hobbyists who enjoy track tuning and setup work. Its compact profile and race-inspired contours make it a practical choice for builders wanting a reliable starting point for upgrades.

Shell and Styling

The clear polycarbonate body keeps weight down while offering good impact resistance, helping the model stay quick on straights. The design echoes professional race cars and arrives unpainted so you can personalise finishes with polycarbonate paints.

MS Chassis and Motor Layout

The MS chassis is notable for its three-part removable construction that makes repairs and modifications straightforward. With the motor mounted mid-ship and a double shaft motor fitted, power is distributed to improve balance and grip during aggressive laps.

Upgrade Paths and Options

• Motor Upgrades: Works with higher performance double shaft motors for improved acceleration.
• Tire Choices: Supplied with small diameter wheels, with alternative tyres available to match track grip levels.
• Gear Ratios: Includes a 3.5:1 gear ratio which can be changed for specific course demands.
• Chassis Tuning: Removable sections let you experiment with setup changes to suit different driving styles.

Handling and Track Fit

The layout places batteries alongside the motor to keep the centre of gravity low, which helps cornering stability. The TRF-Racer Jr. adapts well to a variety of Mini 4WD track layouts and is suited to builders focused on incremental tuning.

With its modular MS chassis and balanced motor placement, the Tamiya 18613 TRF-Racer Jr. is a flexible kit for racers who like to tweak setup and test changes on the track.
