V12 Engine Building Block Sets, V12 Engine Model Kit That Runs, MOC Engineering Model Building Kit with Battery and Motor, Engineering Building Blocks for Adults (3472 PCS)

I thoroughly enjoyed building this kit. It was very complex and challenging but not so much that I wanted to give up. The end result is an amazing, working model of a v12 engine and gearbox ~ absolute joy to build and worth every penny. The one downside is the instruction book is not very clear, I had to use a magnifying glass for some of the pictures. Normally I download the instructions onto my computer so I can zoom in but not available for the engine series. Still - a great kit and heartily recommended.

Very nice building set. No mising parts. Good present for peoples who like enginiering. Very helpfull seller. +AAAAA service

Not sure about this its a christmas present but I know the person is gonna be mega mega pleased

Good model but difficult to build, experience required.

Only just started build still on bags 1 & unable to compete as part missing X2 of the bars & X1 of the other piece shown in the pictures very disappointed as cost alot of money

Great in-depth build. As good as Lego, but without the higher price.

I do a lot of Lego. I was sceptical but absolutely no complaints. The instructions are really good.

The engine has far too much drag and has difficulty turning, this means it only works in the two lower gears. The drive chains tend to come apart which is annoying. The gearbox on its own works perfectly well. Even so it is good to build and looks the part when completed. If you just want it for the pleasure of building it it is value for money. If you want to play with it not so much.
