I had so much fun building this project. It all came together very nicely in the end. I would have given 5 stars if the instructions were a little better. They were very detailed and accurate. The pictures are too small, and I have great vision. I had to take pictures with my phone in certain cases and zoom in on them to know exactly what I was doing. I would gladly pay extra for online instructions that can be zoomed and even rotated. I'm very happy overall and will buy another!

Awesome little engine! This is a very well built product. I bought this for my 11 year old nephew who likes science and anything with an engine. He absolutely loved this gift. I like it so much, I think i'm going to get one for myself too. I highly recommend! On Side note: The engine I recieved did have a small defect which may have been caused during shipping. I emailed the company and they quickly sent me a new part with a spare just in case. I was easily able to fix the issue. Great customer service from the company. Very happy!!!

After I got the package, I checked the parts first. The parts are complete, and the instructions are very detailed and easy to use. I will assemble the wings first, and then I will post some of them, and I will post comments when I have finished all of them

A challenging puzzle but fun to put together and is a great conversation piece well worth the money and it being made of quality metal will last for generations. I have purchased the 1064 piece bull which I am doing now and the 1600 piece Bluetooth scorpion.
