Bought this for my husband as a birthday gift, I really did not actually know what I was buying as engines don't interest me at all. Well he loved it , had it going within minutes and he really enjoyed it. so if you like this sort of thing can't fault it, quite well made as well. well packed and no damage
This stirling engine worked great with no problems. Even all the parts were in the box too RUNS PERFECT!!!!
The craftsmanship and quality seems very high.
Fun little novelty
This V4 engine is really well built and looks great sitting on the table. It runs great too. The description says it runs at 1300-1500 rpm, but mine runs at a consistent 3000 rpm with no load (led) attached. I'm really impressed with this engine, and I'll probably be buying some other designs from Enginediy . Must have for any gearhead/mechanically inclined person!
