The UGM-11 truck represents a new generation of mechanical UGEARS models with more sophistication and features. This model runs, steers, and accelerates like a real truck. First, we "refuel" by turning the lever on top of the cabin. Then, you "start" the engine by shifting the gear lever into "Neutral" and admire the pistons moving very realistically under the hood. Open the cabin door, and you'll see a fully functional steering wheel and gas pedal. Ready for the ride? Shift the transmission into "Forward" or "Reverse," and your truck will rush back towards the fields to pick up another load of hay. We call the UGM-11 truck 100% "Rubberpunk," a perfect blend of clockwork and steampunk worlds. We intentionally designed this model to be open and visible, so even a casual observer can marvel at the wonder inside. This kit will take some time to assemble, but the reward for all who love mechanics will be simply unmatched. Assembly time: approximately 10-12 hours.
