TamTech-Gear is Tamiya's new genre of R/C buggies that are compact in size, yet packed with power and high performance. The third release is based on the classic R/C Fox, and features a campy blue and grey colour scheme. Lightweight 2WD chassis features 4-wheel independent friction damped suspension with fully adjustable shock angle positions. Adjustable slipper clutch and full ball bearings secure optimum transmission efficiency. Ball differential, rear-wheel drive train and universal drive shafts included as standard parts mean that the TamTech-Gear Fox is much more than just your average mini-R/C car.
Tamiya never stated the scale of the GB-01 chassis or the models using this chassis. So scale is unknown, but calculating wheelbase difference between the models and the 58000-series counterpart gives a good indication that the GB-01 models are 1/14 scale.
