Tamiya 18613 TRF-Racer Jr. is a high-performance 1/32 scale racing car model from the Mini 4WD PRO series, created by the renowned company Tamiya for enthusiasts of high-speed driving and professional Mini 4WD racing. This model stands out thanks to its advanced MS Chassis design, featuring an innovative three-piece system with a centrally mounted motor, providing optimal weight distribution and a low center of gravity—key aspects affecting grip and car handling on the track.

The main features of the kit include a transparent and lightweight polycarbonate body, which is easy to remove or paint using special Tamiya paints. The body is pre-trimmed around the wheel arches, and the rest can be finished with household scissors. The included 130 Double Shaft Motor allows efficient power transfer without the need for a drive shaft—this solution is characteristic for models using a mid-ship motor layout, so that both the front and rear axles are driven directly. The car is powered by two AA (R6) batteries, mounted symmetrically on both sides of the motor.

I also recommend this model to intermediate hobbyists—the instructions are clear and the assembly difficulty is rated 2 out of 5.
