Ugears top fuel dragster

UGears Top Fuel Dragster  The model is driven by a powerful spring motor and gear set that transmits power through the crankshaft and belt drive (a rubber band passing through a tensioner with roller) to the rear wheels, which have special silicone gaskets for extra grip. The DIY wooden model has a Start/Stop button, variable driving modes, and is able to rear up on its back tires when peeling out, just like a real dragster. The Top Fuel Dragster has an open "skeleton" body, revealing the beauty and amazing inner mechanics of this racer.

To operate the model, make sure the "start/stop" switch is set to the "stop" position, then twist the non-removable winding knob at the back of the Dragster about a dozen times in a clockwise direction. Place the Dragster on the floor and while holding it with one hand, flip the "start/stop" button to "start," then release. Because this is Ugears, and because we love including realistic details that add that "wow!" factor, in the "stop" position, the air intake dampers are closed and in the "start" position they open!

Real top fuel dragsters have an engine life cycle of just 3 minutes, including warm-up. After each 4-second run they are disassembled, inspected, and cleaned; damaged or worn parts are replaced (clutch, pistons, connecting rods, rings, spark plugs); and the engine completely rebuilt in about 40 minutes, to be ready for the next run. Mercifully, our stunning DIY wooden model Top Fuel Dragster doesn't require that level of maintenance, but do take care in construction to properly sand and lubricate all moving parts for optimal function.
