I the Silenus, so I went out of my way to get a Mojo because I read it was the exact same yo-yo, except in plastic vs. metal. And then when the Dominator came out, it looked an awful lot like a bimetal Silenus, plus the copy says
The Dominator inherits the mojo shape re-interpreted with a beautiful bi-metal design
ā¦ so I got that too.
Is it valid to claim that these three yo-yos, the Dominator, Silenus, and Mojo, are functionally āidenticalā except for the different materials used?
As you can see in the above pics the overall shape is indeed nearly identical, minus a tiny bit of diameter which you can only see if you stack them next to each other on a table.
Going by the specs, Iām not sure:
Weight
Width
Diameter
Dominator
64g
46mm
56mm
Silenus
68g
47mm
55mm
Mojo
67g
47mm
57mm
The most notable item in the specs is that the dominator is perhaps a bit lighter than it should be?
Clearly the rims are notably different on each, probably due to the materials used ā itās striking how chunky the plastic rims are, less chunky in aluminum, and downright svelte on the bimetal Dominator. I wonder if the slight differences in width and diameter between each three (generally 1mm or less) are related to materials?
The cup is different in all three as well but is that purely down to materials as well?
There are few other yo-yos we can play this game with, most notably the Skyva?
People sometimes mention the Silenus is a bit heavy though it doesnāt feel that way to me. If you want something like a Silenus but āfloatierā, the Dominator is that. It is the Silenus-lite. Part of it is slightly less weight (5 percent?) but also the hand feel because the edges are thinner and more resonant. The Silenus has a huge metal axle as well and I suspect thatās where some of the weight difference is because the dominator has a noticeably shorter axle.
I find it hard to compare plastic and metal because the density of the metal makes it feel so different in hand, but thereās no denying that the Mojo is exactly a plastic Silenus!
Ehhh, NO!!! Due to the materials and their properties they will play differently. Obviously most of you kiddies probably have missed this, but the YYJ Hitman and The Lyn Fury were the same shape, thus looking identical. They should play the same you sayā¦ WRONGO. the diifference in materials led to a vast difference in weight distribution and thusly, a vast difference in how they played. Love the HM and to this day dislike the LF.
The YYJ Dark Magic and the Legacy are further examples. The legacy is an all plastic version of the DM, another fine example of a plastic yoyo with aluminum rings. They also play different from each other even though the Legacy incorporates a steel washer under the caps for added rim weight.
Companies often base shapes of new models off of previous releases. Itās great for explaining the design inspiration and purpose while giving the yo-yo an interesting background story, but doesnāt mean they will play the same.
Fair in case of plastic and bimetals as those are radical differences in material. What about the exact same yoyo shape, down to the millimeter, in 6061 vs. 7075?
For example, I have an AceYo gravitation in 6061 and 7075, best I can tell they are literally the same in every way except the type of aluminumā¦ I need to test it blind and see if I can tell which is which in play without looking at them.
Weight wise we got 65.2g for 7075 versus 64.7g for 6061. I took off the bearing and string to make it as equal as possible, Iām assuming the axle is the same width (I would prefer not to remove as I loctite in the non-hex side on all my throws).
A 0.5g difference isnāt completely insignificant, is it? I mean, yoyo companies make a point of mentioning whenever they shave a gram or two off a model, which means half a gram is a numerically meaningful quantity.
Half a gram isnāt major but itās definitely noticeable and can make a little difference. When the Summit was being made they actually made a prototype .5g heavier to see which one they liked better.
I also remember David mentioning one time they were testing Paul Dang and he could tell the difference of as little as .02g or something crazy like that
Yeah, .5g is noticeable and it looks like the cup is slightly different too. It may be a very subtle difference, but if you ran through the same tricks a few times on each yoyo youād probably notice it.
Differing weight is a side effect of trying to get a similar weight distribution with a less-dense & less-strong material. Iād expect a difference like this for any plastic ā metal pair of yoyos, and is probably the main reason why they will play so differently.
Identical yoyos with different materials are identical in different ways making them not quite identical while being incredibly different. I would be indifferent to this question but I need to identify my differences to be identical in my perspective to those responses that preceded mine which are identical but yet different. Confused?
Per the digital scale, without string (but with bearing and axle) the 6061 is 65.1g and the 7075 is 66.7g.
These are definitely identical in shape, cup, everything that I can see. Interestingly these weight numbers are almost exactly what I read on the YoyoRewind store spec pages at 65.1g and 66.8g
(also question for @YoYoExpertGarrett ā do weights usually include bearing and axle? I guess they must since my measurements track the official specs so closely, at least on one yoyo store website? How much variance is there in weight from the same model of yo-yo if you measure say 10 of them? Do you guys weigh & measure the yoyos you get yourself or do you reprint the specs from the manufacturer?)
I guess this is consistent, itās the second āidenticalā yoyo pair differing only in materialā¦ and the 7075 is a bit heavier in both cases, because it is denser and stronger?
6061 is 66.6g, 7068 is 64.1g ā as usual measured with axle and bearing in place but no string.
That is a bit weird since the shape looks 100% identical to me, and 7068 should be denser and stronger? Iām unclear if stores measure these figures from the actual yoyos they have on hand ā¦ ā ā ā ā ā ā ā ā ā ā ā ā ā ā ā says

Thatās a 4.4g difference! I measured only a 2.5g difference (66.6 - 64.1) in the two I have on hand.
Ah yes, youāre right, I see it now. Thatās about the only difference I can see. Itās reflected in the corresponding inside edge as well, a slightly more angled bump there on the Ultra.
Still doesnāt explain how yoyorewind would measure nearly twice the weight difference than I did between the two models
