Customer Reviews
Great deals and quick shipping
Saved about 20% on the Stirlingkit steam engine model. Shipping to the US was fast, got it in about a week. Codes are easy to use at checkout.
Cool kit, could be faster delivery
I ordered the 4 cylinder engine kit, and overall I'm happy with it. The assembly instructions were mostly clear, though a couple of steps took a bit of head-scratching to figure out. The parts fit together well and the finished model looks really good on my desk. It's a real working model, which is super cool. My only minor gripe was the shipping time. It took about 12 days to arrive in New York, which felt a little long. I know these things ship from a ways away, but I've had faster service from other international vendors. Still, the quality of the kit makes up for it, and customer service was quick to respond when I asked for a tracking update.
Good deal on a steam engine
I was looking for a new hobby project and stumbled upon Enginediy. I ended up getting the horizontal steam engine during their anniversary sale. I paid about 15% less than I expected, which was a nice surprise. Shipping took about 10 days to get to California, but it was free. The kit itself was well packaged, and I'm really impressed with the quality for the price. Definitely felt like I got my money's worth and then some. It's a solid kit.
V8 engine kit is awesome!
I just built the V8 engine model kit and it's incredible! The details are amazing and it actually works. It took me a few evenings to put together, but that's part of the fun. I'm already eyeing my next purchase, maybe a turbofan model. Enginediy, you've got a customer for life!

Can you actually use the fuel for the miniature gasoline engines or do you buy that separately?
Are these kits really beginner-friendly? I'm kinda new to model building but wanna try a V8.
Thinking of getting one of the V8 engine kits for my dad for Father's Day. Anyone know if they usually have a sale around then?
Hey, wondering how long shipping takes to California? Trying to get a kit before my nephew's birthday next month.
Has anyone compared these to Stirlingkit or Enjomor? Curious about the quality difference for a V8.
