Mould King V12 Engine Model Kit That Runs, MOC Engineering Model Building Kit with Battery and Motor, 3472 PCS STEM Engineering Building Blocks for Adults

Amazing model. Got it built in 3 days, working on it about 5-6 hours each day. Runs smoothly and looks great. Instructions were very clear and easy to follow.

Great alternative brand. A few steps confusing but overall A great build

This is a fun build, but beware, it can be complicated as well.

Took a while to put together. Some instructions aren't real clear. Once together it's great. Actually runs. Good price.

This kit was amazing. Its been a few months since purchase ans i still play with it from time to time. Smooth gear shifting, chains move freely, cams and crank are smooth. Great gift for a gearhead who also loves their childhood memories of building blocks. Worth the money. Easy instructions to follow. Had all parts. Still holding up strong.

This is the worst model I have ever attempted to put together I do not recommended it it really sucks😖😖 I will send it back and request a refund Don’t buy it

Brother loves it. Very challenging.

A great product, however the illustrations in the instruction manual could be clearer. I have built many Mould King products over time but this one was the most challenging build as of yet.

Very large engine build. A lot of detail from crank shaft to cams, valves and timing chains. Realistic appearance. Interesting speed gearbox. This was challenging and instructions are good. Some parts need glue to hold in place.

C’est super à construire

Very good model .Lots of fun to build. Only problem there was 4 pieces missing. Two in the transmission. It work just the same bit only one gear instead of four. Also two blocks missing which did not cause a problem. Wish there was an easy way to get the missing parts.

This was a fun build , but was missing a sprocket/gear wheel for the transmission Should put a couple extra in bags

Missing pieces. Cannot finish. Very disappointed.
