The Classic Tamiya Monster Beetle. The Iconic RC kit.

This version takes the classic body, shrinks it to a smaller scale, and mounts it on a variant GF-01 chassis called the GF-01TR!

The GF-01TR fits the gear-driven GF-01 chassis with reduction gears (also known as portal axles). This modification allows the hobbyist to better transverse trail terrain as it lifts the bottom of the chassis to better clear obstacles that could high center the vehicle and render it stuck.

GF-01TR Chassis

This gear-driven 4WD chassis is based around a lightweight and tough monocoque frame, with power provided by the centrally-positioned motor. Reduction gears on each axle slow drive shaft rotation for immense traction, great ground clearance, and the ability to take on tough off-road terrain. The gearbox is sealed to protect from dust and debris, and integrated into the frame; built-in differential gears provide superb traction and durability with the use of included diff putty. 4-wheel double wishbone suspension utilizes friction dampers, while a 2-piece tie rod steering setup with the servo on the left gives excellent response. Yellow wheels are fitted with 115mm diameter hybrid pin spike/lug pattern tires for superior cushioning and grip. The chassis utilizes a ‘square’ setup with similar tread and wheelbase lengths.
