Really nice model!
by cyndia (5 out of 5 stars)

Got this as a Christmas gift for my husband who loves to put things together. As soon as all the kids left he pulled it out and started it. He spent a couple of hours working on it and is fairly close to being finished. It's apparently a great kit since he didn't utter one curse word or sigh during the entire construction of it. And it's a lot larger than I expected.... All in all, Santa did well ; )

Great kit, but...
by PennyLane (5 out of 5 stars)

This was my first time putting something like this together, and it was grand. All the pieces were there including 1 extra 4 cm gear dowel, and went together correctly and fairly easily. So the directions are pretty comprehensive. My only hiccup was the section on attaching the canopy.. If you want to be able to play with the amount of luff the canopy has more precisely between its horizontal supports and be more flush with them, for a generally better looking finished product. The best way it would seem to me, is to follow only half of the first step in the attaching the canopy section. Line the canopy up like it says, and instead of 2 put 1 dot of glue only on the inside of the top horizontal support. Then pin the canopy in place with one of the little clothes pins that came with it, where that other dot of glue would have gone on the outside edge of the top support. Then follow these same steps on every support, to the last support of the the first piece of canopy. Checking and adjusting the canopy as you work your way down each. Then go ahead and do step 3 of attaching the first piece of canopy, and then finally do the second step last. Allowing you to adjust the amount of luff and how flush the canopy is as you glue the outside edge to the downward spiral. Same idea for the the second piece and steps for the canopy. This method however will likely require trimming of the excess canopy cloth when finished like the note says. I'm letting any interested reader know all this because I missed the footnote that tells you the canopy may require trimming. Until after it was already glued, and the directions look as though they're telling you to line up and glue the edges of the canopy and the downward spiral as if the cloth was going to line up and fit just right the first time. No worries though, I made it look not so spottily luffed with some careful trimming on the inside egde, and creative adhesive work. No random foreign language problems, and the tube of glue could've used another ounce or two. Just coated mine with a 15 spf lemon oil which gave the whole thing a ton more character.

Great set

We bought this for our engineering minded son. It took him about 2 hours to build (he is 14). It stands a bit taller than we expected. You have to be a careful you don't turn it too quickly or the gears won't match up. The materials appear to be of good quality.

I love these! We have purchased a few of these DaVinchi kits and we are 30 year olds and we enjoy them! Tons of fun for kids too! Great learning tool, and you get a wicked working device after you're done! I wish they sold more wood kits but this one is worth buying!!

My daughter was able to assemble this kit very quickly with the instructions and equipment provided. Looks good! She used it for a presentation in her history class (yes, she admitted it was from a kit), and the teacher kept it for his classroom.

Beautiful and Educational At the Same Time, like all of Leonardo's Works
by Mark S. Williams (5 out of 5 stars)

An excellent product, designed from a single drawing by Leonardo. Quality of materials is excellent. Assembly is thoroughly and entertainingly laid out. Being American, I'm unfamiliar with the metric system, which, of course, is used by this Canadian company. I was able to identify similar parts by comparing lengths, though. Instruction book also covers the historic and scientific aspects. The model is beautiful. I use it as a centerpiece on the dining room table!

Very nice model to look at
by Heather Opiela (3 out of 5 stars)

The instructions were very clear; however, the pieces were "off" and didn't fit together properly. Holes didn't line up. So, center pieces were crooked, the crank wouldn't turn and the canopy wouldn't spin. Very nice model to look at, but my nephew wanted it to "work" correctly. So, we're sending it back.

Great looking Davinci artifact!
by Jen Jeffries (4 out of 5 stars)
July 17, 2018

Having no real building or assembly experience beyond that of, like LEGO and Lincoln Logs, I would say it was relatively easy to put together. It doesn't spin extremely well and I may have got a little carried away with the glue on the cloth (it's not super attractive to see the glue through the cloth). However, as an artifact for my classroom it's a great piece for discussing Davinci and does actually work. It took roughly 4 hours for me to get together and the instructions are fairly easy tonubderstand. So yeah, worth it!

wood model

Very cool model. Decent, sturdy materials. The sail is a little tricky to put together--to glue it down properly in its intended alignment. Read the instructions all the way through once before you start. Better for a teen or an adult and not a younger child.

This is a great kit. The packaging has some nice artwork, and the instructions were clear and good for kids and adults.

The instructions also include some information about Da Vinci which is a nice touch.

I especially enjoyed the snack break as recommended by the instructions.
