Customer Reviews
Good value on an engine kit
I was looking for a V8 engine model kit and saw Enginediy had a good offer. I signed up for their newsletter and got a discount code for 10% off, which made a difference. The total price felt fair for what I received. Shipping took about 8 days to get to me, which was fine. Overall, I felt like I got a good deal and the kit seems well made for the price I paid.
Fast shipping, quality product
Ordered a 4 cylinder engine kit. It shipped quickly. Arrived in 6 days. Kit was complete. Parts fit well. Good quality. Would buy again.
Always reliable, great kits
I've ordered from Enginediy a few times now, and they've been consistently good. This last order was for a radial engine model, and it arrived in about a week, same as my previous purchases. Everything was well-packaged, and all the parts were there. It's why I keep coming back; no surprises, just solid products and dependable shipping. The instructions are always clear enough to follow.
Mostly good, some small issues
I bought the transparent engine model. The kit itself was good, and the transparent parts are cool for seeing how everything works. Assembly was mostly straightforward. My only small gripe was that one tiny screw was missing, and I had to find a replacement in my own toolbox. Customer service was polite when I asked about it, but it took a few emails. Still, the engine works as described, and it's a neat display piece. For the price, it's a solid purchase, just double-check all the parts when it arrives.
My steam engine is amazing!
Oh my gosh, I just finished assembling my new horizontal steam engine model and it's incredible! The detail is fantastic and it actually works! I spent a whole weekend putting it together, and it was so much fun. Every piece fit perfectly, and the finished product looks awesome on my desk. I'm already eyeing my next kit, maybe a Stirling engine. I can't wait to buy another one!

Hey guys, thinking of getting one of their V8 kits for my dad. How long does shipping usually take to California?
are these kits good for someone new to models? i'm interested in the 4 cylinder but never built anything like this before.
