Machine Works Build Your Own 4-Cylinder Engine Toy - Replica Model Building Kit - Features Augmented Reality, Sounds and Illumination, 100+ Pieces, 10+ Years

Requires some good hand skills to avoid breaking the parts. All parts are plastic and delicate which can be damaged if over tightened. I have assembled it with my 10 years old who enjoyed too much.Overall it is good staff with fair price.I would advise the supplier to provide some spare parts with the kit. Loosing one small item would seaze the entire project.

cheap material, easy to break and steps are not very clear. It was misleading. there was a step that I exactly followed and the piece broke now I can’t complete the set and can’t return it!

القطع بلاستيكية و تركب مره و حده و لم تستطيع ان تتدرب عليه فقط للشرح

The crankshaft gear does not mesh with the crankshaft sprocket.that the timing belts are attached to.the gears dont even touch each other.pistons move.but sprocket doesnt.which means timing belts dont move.so valves dont move.the problem is the kit came with 2 distributor crankshaft gear C.did not come with cranckshaft gear B.

Cumplió con las espectativas

Entretenido, calidad de las piezas notable… mi hijo ha disfrutado mucho montándolo.

Ai miei figli di 12 e 14 anni è piaciuto moltissimo. Per quanto ho speso (50 euro) il prodotto è davvero ottimo ed è perfetto a scopo didattico. Suggerisco di limare con cura tutte le sbavature della plastica perché sono tutte parti in movimento e non devono fare attriti. Unico difetto minore è che non abbiamo trovato nelle scatola le aste metalliche degli alberi a camme, ma abbiamo facilmente risolto spendendo ben 70 centesimi al Brico. In merito al funzionamento è stupefacente e molto ben progettato. Ogni tanto si avverte che l'ingranaggio del motorino non riesce ad agganciare bene l'albero motore e perde un colpo Piccolo difetto che gli perdoniamo visto il prezzo. Approvato 👍🏼

This is a pretty cool kit. Some of the parts have a lot of moulding flash so some work with a craft knife, file, sandpaper etc will be necessary if you want this to fit together as well as it can and look as good as possible.I built it with my car mad 15 year old daughter and it does show the basic mechanics of a V8 very well. I'm not convinced many 10 year olds could manage this unaided. The very many screws are tiny but thankfully all the same and there are plenty of spares.It has two distributors, one for each bank, driven off the cam shafts which is not usually how a real set up is and these are, again a little bit fiddly to install. You need to read the instructions! Nevertheless it all worked first time. We used some tiny zip ties to tidy up the ignition leads and hold them away from the exhaust manifolds.On the whole, really pleased. It looks great put together.
