Mould King 13112 RC Excavator Building Set for Boys, 1830 Pieces Building Blocks APP Remote Control Truck Construction Vehicles Model with Motor, STEM Engineering Toys for Kids

Definitely advanced but a fun build and the controls work pretty well.

Very nice. Pieces fit together well. All there everything works.

This is a great build!Drives great, operates great!Only downsides: 1) you have to turn the remote off/on if you want to switch from driving to using the bucket.2) the drive control is reversed on each side so to go forward one side is the top button the other is the bottom button. Tried to fix that but failed.3) the bucket is WAY, WAY to big. You can't pick up anything because the weight is too much for the gears. I tried picking up a half bucket of dog food (it was there. Lol) and the gears just clicked or stopped all together. I have also never seen an excavator with a bucket that size (proportion wise) in my life. it looks like they used the bucket from a loader for this model because they didn't feel like making one specifically for the excavators.If they put the right size bucket with this it would be PERFECT.Maybe I'll make one out of ABS sheet for it. Lol

This Mould King 13112 RC Excavator Building Set is a total game-changer for boys who love construction toys. With a whopping 1830 building blocks, this set lets you create an awesome remote control truck construction vehicle. The best part? It comes with an app remote control and a motor, making playtime super exciting. The only downside? Some might find the assembly instructions a bit confusing at first. But once you figure it out, it's pure fun all the way! 🌟🔩🧩

If you just want to build a unique and well engineered mechanical model for the joy of doing it, then this is GREAT value. If all of your problems are first-world, you have $500 to burn, AND you demand the absolute finest quality control in every respect, then buy yourself some lego and what are you doing even looking at this?Anyway, I was consistently impressed with the fit, design, and features throughout. The instructions are FINE. There was no point where the quality of instructions was nearly as low as the price. I expected absolute trash based on the price! But this set was clearly produced with much more care than chinas typical level of effort when producing knock-off type products. The parts fit together in a consistent and surprisingly precise way( not as good as lego but way better than COBI). They consistently exceeded my (minimal) expectations with sufficiently detailed instructions, and mechanisms which were engineered with a clear priority for high functionality and aesthetic over cheap simplicity.

Missing parts. Instructions could be better illustrated

I liked everything about this it was very interesting to build and to see how it all worked when it was complete. I would like to see Mould King make a variety of this same concept (farm equipment with farm attachment, Fire Trucks, Tractor trailers, and more construction equipment. I have built 4 already and have 3 more to build.

Missing pieces from each bag that has been opened. First missing piece was replaced after pictures, descriptions and verification of Amazon purchase order. Now after more missing pieces was sent an email to open all remaining bags to check for parts that aren’t supposed to be in them. Why aren’t appropriate items in correct bags? How many more parts are going to be missing from yet unopened bags? It’s not worth the cheap price for this item. Bought this for my children, so far a disappointment. This is what happens when you try to save money, you get poor quality and service. Stick to LEGO!
