What a beautiful piece of engineering. The quality is excellent. Everything turns smoothly. I haven’t start it yet but sure it will run smoothly as a similar engine.
absolutely beautiful little engine very very happy definitely will be buying more, i 100% recommend these models, would absolutely love it if they had a piston ring upgrade kit instead of having Orings
I have purchased all of Banggood`s supplied miniature engines and the quality just keeps getting better with each offering you could not build these engines at the price being offered. Top marks to the manufacturer.
Very nice model very well machined looks excellent was happy to add it to the collection thank you
A super fast delivery and a beautiful little engine!! That was a top performance!!
Great engine, runs very well. Quick delivery.
a wonderful almost vibration-free running motor in almost perfect execution.
This is a smal peace of art, it runs amazing, nothing more to say
This is a delightful little model. Satisfying to watch run with all of the connecting rod assemblies in full view. It goes almost an hour on a tank of white gas or petrol.
Beautifully made machine. But it only runs for about 15 seconds. Then it needs to rest for half hour to run again. I tried various settings on the very sensitive air/ fuel valve. 1/4 turn from closed, as per instructions, is the best.
