Small yet perfectly formed

The Lunch Box is a famous name in Tamiya R/C and Mini 4WD, delighting many a hobbyist over the years. Now, it is here in brand new mini 1/24 form, as a fascinating R/C model assembly kit! While extremely compact, it is endowed with excellent mechanical design: gear driven 4WD, strut suspension and more! The lightweight polycarbonate body comes pre-painted in yellow, with wheel arches pre-cut and body mount holes already made. Stickers are included to decorate the body.

SW-01: Super-Compact 4WD

190mm long and 150mm wide, the SW-01 is a compact, highly fun 4WD chassis. A Type 370 motor is central in the slim monocoque frame, with gears transmitting its output to the front and rear of the model, where 70mm tires translate it into a powerful drive. The chassis power source is mounted in the top section to allow wild wheelies under acceleration. Strut type 4-wheel independent coil sprung suspension utilizes single piece upper arms to link left and right wheel steering motion, helping suppress roll during turns, and together with front and rear differentials realize a tight turning circle.

This is a compact, maneuverable, and above all super-fun addition to the world of Tamiya wheelie models! It's a familiar face, too, as the legendary Tamiya Lunch Box has been shrunk down to 1/24 scale.

The classic shrunken Lunch Box body sits on top of the 4WD SW-01 chassis. It is capable of 4-wheel steering using separately sold Upper Arm Connectors that not only allows you to steer with all four wheels on the ground, but it also allows the vehicle to steer while doing wheelies!
