This engine is well built and has a lovely finish. I expected it to be fun to change the flywheel to see what effect it has on the engine speed and also fun
to see the small "generator" light up the bulb. Unfortunately the engine did not arrive with the extra flywheel nor was an allen key included, so the flywheel could not be changed. Also the bulb did not light up. When running this engine can only produce about 2.5V, so the 5V bulb is never going to work. A nice example of an alpha type sterling engine, but I cannot rate it more than 3 stars because of the missing items
This engine runs fantastic, the problem is that the engine they sent does NOT match the item in the picture. I specifically wanted a thermoacoustic stirling engine with an "extended" hot tube. What they sent was the standard "short" hot tube variety. I already have 3 engines of this style, if I wanted another I could have purchased the one from this site for $23.99 or $19.99. Instead, I paid $29.99. This engine comes with bearings in the flywheel mount so it runs exceptionally fast. It is a great engine overall, but unfortunately not the engine in the sales pictures. Based of performance this engine is "5 star", however Sterlingkit should never substitute engines without customer authorization first
Well I have built this little engine was fun to build took me from 11pm to round 7 am the next morning as I was taking my time going to put it on a stand then start it up just waiting for the stand/base for it
A nicely packed kit love how the box is wood and everything is packed in black foam trays instructions are online but the contents are in plastic box’s. Like screw’s nuts and everything else needed to build it
I sent you an email describing my research and asking to speak with your engineers about reversing the rotation. I have had no response. I am a retired electrical engineer researching chirality and Tesla's concepts on Aether and gravity.
