Mould KingL4 Engine Building Blocks Sets, MOC Inline-Four Engine Scale Model Kit with Battery and Motor, Collectible Set for Adults, Construction Toys for Kids Children Boys Girl(1787 PCS

Surprised by the detail and complexity of these kids! I have put two of them together and was challenged by the builds.The number of parts is a little overwhelming at first but most of the parts are used in order if the labels on the packets but not all! One if the models had two complete sets of numbered packets of parts, so it was a little confusing but the instructions are very clear and I think anyone can follow them if you have the patience to follow them. Each step is short and easy to complete.I can't wait for my grandsons to get old enough to build these! The details and custom pieces are far better (and cheaper) than the original brand of bricks. Every time I check, Mould King had released another model with even more detail!Wouldn't hesitate to recommend to anyone!

Not challenging enough for my son but it was fun

The media could not be loaded. This kit will take someone who is detail-oriented 6-8 hours to complete. The model has perfect symmetry as built and the parts fit very well and are molded nicely.It would be a good idea to have simple hand tools available to assist alignment and assembly of some parts, or for disassembly if you make a mistake. The valve covers are opaque, not clear like the pictures show. You can still see the piston motion, however, so not a big deal.Wear finger cots for a better result.I have built several models of different types over the years and the quality of this kit is light-years ahead.It is well-worth the money considering the challenge presented and amount of time it took to assemble.

Unless you are fond of frustrations, I would advise NOT to attempt to put this piece of crap together! There are NO instructions except pictorial suggestions. The pieces are NOT numbered, and the pictures are misleading!You will have to rummage thru the entire set of pieces to find the ones to put together.Update: This is by far the worse piece of junk I've ever attempted to put together. The pictorial instructions are misleading and even incorrect and/or false! There are NO WRITTEN instructions, and one has to rummage through pile of pieces to find the possibly correct next assembly point!I will repeat: Stay away from this piece of junk unless you have frustration phobia!

it was an impressive engine. enjoyed building it. going to give it to one of my nephews as a christmas gift

The media could not be loaded. I was impressed by the detail and quality of the parts and the assembly instructions. I would not say it was super easy to assemble and I had to take my time but was fun to build. If any 8 year old can build this kit by themselves, they need to be working at NASA today. If your vison is less than perfect like mine do yourself a favor and download the PDF so you can zoom in on the steps on your laptop. Can be hard to see in the manual. The PDF also has a link to download the mobile app for the model. I did some early testing with the electric motor to make sure the crankshafts were all working correctly. It was fun to watch the crankshafts turn and the pistons go up and down. It was a bit of a shame the crankshaft and cams were mostly covered by other parts and as another reviewer mentioned the cylinder heads are opaque instead of clear. Would have been nice to be able to see the pistons going up and down and other internals more clearly. I consider the purchase well worth the money.

Kid loved building this
