Mould King 10088 V8 Engine Model Kit - 535 Pcs to Build Your Own Mini Engine That Works - DIY STEM Mechanic Engineering Construction for Kids/Teens, Hobby Building Blocks Kit for Adults

The model was very easy to assemble. Good value. My Great Grandson put this together is just a couple of hours. He's ten.

This Mould King V8 engine kit is a well constructed kit. My instructions manual was accurate with no mistakes. Look closely at the color of part in manual. Some parts are identical except for their color. They will work if in the wrong place but intended color scheme will not be correct.. I too had to glue the black gear shafts the hold the crank shaft to engine mount at both ends. They can come loose during operation and stop engine. The red crank shaft end peices should alliw for more of the gear shafts to fit deeper into part.This problem is why a only gave it 4 stars.

I bought for my grandson who is 12 and loves cars. He was thrilled with it.

I bought this as just something to do and the first order arrived was missing a part. Could have been more but I only got through a bit of it. Returned it and received a new one. This one was almost complete and one of the parts was not long enough. Complete garbage. I will not be ordering anything from Mould King again. Instructions were just ridiculous to get through.

Grandson put the together in one afternoon and was excited when it actually worked! It was challenging enough and the instructions were easy to read and follow.

Great model, purchased as a present for a brother but one of the crankshafts is missing a piece so I cannot finish putting it together. Trying to figure out how to get a replacement part.

This snap together kit was fun to do. The pieces are well made and fit securely. The 6 or 7 bags of pieces are numbered, but I could not correlate the bag numbers to the instructions, so I dumped each bag into separate plates. You must look very carefully at the illustrations (I used a magnifying glass) to make sure you are selecting the correct piece as many look similar. The pieces are not labeled (stamped with a number), and the instructions don't indicate which bag to find the piece in - indeed the same type of piece may have 30 in total but be spread out over more than one bag. The engine ran once the kit was completed, so I achieved success, but it would have been much more satisfying having more detailed instructions - maybe that is asking too much for a company that sells these kits worldwide.
