Karei V8 Engine Building Set 1065 PCS- Manual & Electric Dual Working Modes
About this item
- [V8 Engine Model Kit]: This is a cool classic 8-cylinder internal combustion engine. It highlights and details all the important features such as moving pistons, valves, turbocharger, and exhaust system. You can see crankshaft, fan, and a super charger, all driven by chain belts, dynamically demonstrating the complex inner workings of a real internal combustion engine. It’s a standout choice for teens, adults, or anyone curious about how engines work.
- [Realistic Working V8 Engine]: It runs like a real engine! Once assembled, you get a hands-on look at how an engine works, from the crankshaft to the cylinders, and it really helps visualize concepts that are usually just diagrams in a book. It’s incredibly satisfying to see it “run” and hear the simulated engine sounds whether you are into cars, engineering,or just love mechanical projects.
- [Electric & Manual Operation Modes]: The v8 engine building toy has 2-working modes to add realism to the display. In electric mode, the gear shifter and motor button need be combined to adjust the direction and speed - counterclockwise or clockwise, low speed or high speed. The highlight feature is that it's an USB rechargeable motor, so don't worry about buying batteries. Manual mode only requires cranking the handle (NOTE that the gear shifter must be centered in the Manual mode).
- [STEM Toy Gift for Adults & Kids]: Our V8 engine motor kit is a hands-on lesson in mechanical principles that is perfect for STEM learning, technology clubs or as a challenging family project. This is an excellent lover or family's birthday, Christmas, New Year gift or project. It’s both educational and just plain cool to display and demonstrate. This motor building set includes 1065+ building block parts. It is challenging and we recommend for 14+ kids or adults because of the complexity.
- [Premium Quality Buidling Set]: Karei V8 model engine building block kit made from ABS materials and tested for quality control. It is non-toxic, odorless,highly durable to ensure a safe and reliable building experience. After the assembly is completed, the entire set has a firm structure and will not fall or fall apart easily.
