Description
K4tasche pairs a retro pickup-truck body, moulded in green, with a small moulded compartment inside the rear bed for extra detail. It shares K4 Gambol's low-geared, aero-side-stay FM-A chassis setup, here fitted with dish-style wheels and super-hard low-profile tires, and runs the same 5:1 gear ratio, favouring torque and acceleration over outright top speed. As with the rest of the FM-A base kits in this series, the chassis keeps its forward-biased motor position and low-friction front skid bar, aimed at stable handling through slopes and elevation changes.
- Length 144mm, width 97mm, height 64mm
- Chassis: FM-A (aero side stays), gear ratio 5:1
- Motor included, snap-together assembly
