Our engine quality

A lot goes into making an exceptional model engine.

Good is the enemy of great

We set out to make a great engine model, not just a good one. And we knew that in order to achieve that, we’d need not only the best quality materials and components and equipment available but also factory partners who shared our exacting standards.

Our factory partners

We met with many factories before deciding which we would work with. Only a handful was able to meet our standards of engine quality, but the ones we chose really stood out to us with their level of expertise, craftsmanship, and attention to detail.

Jack – our main factory’s CEO and a seasoned industry veteran – personally inspects finished Stirlingkit engines with the production managers.

CNC Machine Working

We work with 10 best engine factories team to produce different series of engines, like stirling engines, steam engines, 4 stroke RC engines, internal combustion engines etc.. CNC machines are widely used in our factories to control the operation of machine tools that cut, grind, drill, turn, mill, and/or shape it into parts that meet exact specifications. in this case, it ensures consistent product quality. 

Details matter

It took more than a dozen iterations before we perfected all the details: from the refined texture and finish of the engine to the precise alignment of components. All these things might seem unimportant to some, but to us, putting equal thought and care into the little things is how we show respect to our customers. To us, the details make all the difference.

Rigorously tested

See how we put our quality to the engine test (actually, more like 30 tests).

We Care Your Parcel

We hope every parcel arrives safely at every customer's home. So we always choose protective boxes and bags to pack every engine.  We place a thick layer of crumpled paper or bubble wrap at the bottom of the box. Pack the heaviest items first followed by the lightest on top. Pack it tight –Wedge paper or foam peanuts into the space around it.
