Customer Reviews
Decent value on first order
This was my first time buying from Enginediy. I decided on the turbofan engine model. I signed up for their newsletter and got 10% off my first order, which made the price feel even better. Shipping was free on the engine kit, which also helped keep costs down. It arrived within a week. For what I paid, the quality was good, and it feels like I got a good deal. Definitely worth the money spent.
Amazing Stirling engine!
Got the Stirling engine and I absolutely love it! The detail is fantastic, and it runs so smoothly. It's a real conversation starter on my desk. Enginediy totally nailed it with this one. I am definitely coming back for more, maybe a steam engine next. Everyone should check these kits out because they're just awesome!
Engine model kit experience
I purchased the 4 cylinder engine kit. The packaging was good, and all parts arrived safely. Assembly was mostly straightforward, though a few steps in the manual could have used clearer diagrams. It took about 5 days for the order to reach Denver, which was reasonable. The finished model looks great and functions as described. My only minor gripe is that spare parts weren't immediately obvious to find on the website in case I lost something, but I didn't need any. Good value for what you get, especially compared to some others out there like Stirlingkit.
Good quality kit
Bought the V8 engine model kit. Parts felt solid. Instructions were okay. Assembly took some time but it works. Happy with my purchase overall.
Fun project, took a bit long
I got one of the transparent engine models, the internal combustion one. It was pretty fun to put together, honestly. The parts fit well. It just took a little longer than I thought it would, but that's probably on me, not the kit. Watching it run after was cool. No real complaints, the website was easy enough to use and everything got here fine.

Just found Enginediy, looks awesome. Do they ever do like, big sales? Wondering if I should wait for a better deal or just jump on it now.
Hey, thinking about grabbing one of those V8 engine kits. Anyone know how long shipping usually takes to like, California?
