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 fits well for standard 0.33 L cans. Twist the knob on the tanker's cap and unfold it in surprising way. This model is deliberately designed to have a raw, open look so even the casual observer could appreciate the marvels going on inside.\nThe Mechanical Tanker 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 realistically under the folding hood. \nLike all other UGEARS models, the Mechanical Tanker comes with step-by-step, full-colour, truly easy to follow instructions and several spare parts inside.\nThe cutting is well done; each of the parts comes out of the plywood sheets easily. No glue and special tools are needed for putting the model together. You can assemble it at home on the table. Fits together like a puzzle without glue or special tools thanks to UGEARS' patented plywood joints.\n*Assemble without glue like all UGEARS models by step-be-step, truly easy to follow, colour instruction manual.\n*Size Model: 330*180*125 ** (13*7.1*4.9 inch)\n*Package size: 372*170*57 ** (14.6*6.7*2.2 inch)\n*Number of component parts: 594\n*Estimated time of assembly: 14-16 hours\n*Level: Advanced
