Review: Really good engine for kids; instructions are great, and functionality is great, but the chain was wonky and then ended up working. are great and functionality is great but the chain was wonky and then ending up working.

I recommend this because this was my son’s birthday gift and he loves it!!

AN HONEST VERIFIED REVIEW!! Not gonna take a picture of the box. Read you the description and tell you my 10-year-old put it together in a day. Yes with an adult. These kits are challenging to put together because you have to follow the directions exactly. especially with all the moving parts. I’ve built multiple different STEM brands in my day including LEGO. i stopped buying LEGO STEM kits a while ago because they are way overpriced. Not paying for the name! Sorry LEGO people. NO DIFFERENCE WITH MK! This build was great! 👍🏼 as the build went along I made sure all the moving sections were correct. Step 21 is an important one to follow or it won’t shift correctly and lock up. Make sure it locks like the pic. The part on the right clicks in once the part on the left free floats, it connects a couple steps later. & the chain comes with 48 links. Use 46. This was my first Mold King set and was pleasantly surprised. Just started another one a V8 this time. And I have another one coming. Love, the fact it came with a motor to run it. A lot more satisfying to see everything run when it’s done. No missing pieces. Nice tight fit. A lot of different pieces I’ve never seen before. the bags are numbered. Use the bag with no number on it throughout the build. I think for the money and the quality you can’t beat mold King. Especially for what you get for the price. I also included as a pic of my most important tool I use for all my stem kits. Great for part removal & some tricky install moments. I know you can buy stem kit tools. I have one. But this is my go to. Once again nice build Keep it up Mold King.
