Calling all gearheads and tinkerers!
This isn't just a model—it's a fully functional, 1/10 scale replica of a 4-cylinder diesel engine that you build yourself.
With over 300 precision parts made from stainless steel and aluminum alloy, it's a serious (and seriously cool) project.
Once assembled (takes about 4 hours), you can power it up via the included USB cable or its 450mAh battery.
Watch the pistons fire, the crankshaft turn, and the cooling fan spin—it runs for over an hour on a full charge!
It's an amazing way to learn how real engines work.
Perfect as a challenging STEAM project for teens 14+ or a satisfying build for any adult who loves mechanics.
Comes in a nice gift box with all the tools and an English manual.
A unique and impressive display piece that actually works!
