A cool wooden model for self-assembly from the new UGEARS Trucks Collection. Based on UGM-11 Truck, the Mechanical Tanker model has real TANKER with the unique opening mechanism which is a perfect fit for standard 0.33 L cans. Twist the knob on top of the tanker and watch it unfold! Original gift idea, smart and engaging hobby, that brings together fathers and sons and takes grown-ups back to the childhood memories and the world of creation. Based on UGM-11 Truck, the Tanker Truck is equipped with a four-cylinder rubber band engine and moves on its own forward in the “drive” mode and back on “reverse” transmission mode. Start the engine in 'idle mode' and look at four pistons which move under the folding hood.  Made from sustainable wooden materials the kit has all you need for assembly: a set of high-quality plywood boards with precisely cutout parts, detailed step by step instructions and several spare parts inside. Laser precision cut - each part is easily pushed out from the plywood sheets. No glue and special tools are needed for putting the model together. Fits together like a puzzle thanks to UGEARS’ patented plywood joints. Assemble without glue like all UGEARS models with a step-by-step, truly easy to follow, colour instruction manual.
