lube test. Light/heavy/none.

Any comments or does someone else have time to kill and re test using my criteria?

Yoyo: DM-II
String: 100% poly
Bearing : Stock, large C
Response: Flowable

“One drop” means one full drop applied internally and bearing reassembled
“Scant drop” means just a trace on a pin, internal and reassemble
“None” means cleaned and air dried with compressor
“Dead drop” fully wound and just let drop and unwind with no force
“Hard sleeper” as hard as I can throw the damn thing.

Time begins at release of Yoyo
Time ends when Yoyo rolls over

Each test performed 6 times and times averaged.

Results

Dead Drop
One drop, 8 seconds
scant, 8 seconds
none, 10 seconds

Hard Sleeper
One drop, 35 seconds
Scant,50 seconds
none, 60 seconds

The times were exactly the same leaving the shields off.

Ok, but you should be getting more than those times. 10 seconds on a drop is really low.

3

Yeah I get probably 3 to 4 minute sleepers with one or two drops.

4

Did you adjust the tilting during the tests or did you let the yoyo tilt and die out?

5

And thats with a stock bearing?
What the hell could be killing my sleep time?

6

No adjustments during each test, I just let it tilt and die “naturaly”

7

I think that you should use the string tension to adjust the tilt while doing the test to improve accuracy. It is difficult to make sure that all of your throws are at the same angle. If you adjust the yoyo, this factor is eliminated, so it would be more accurate.

Or you can finger flick each… the problem with throwing down a sleeper is when they tilt, and when you counter that tilt you have little variations within each test…

9

Thats why I threw 6 times each and averaged the times.

This DM II has been like this right out of the box. It does not apear to be off balance and the only thing I can come up with is to think the bearings suck. I have a Konkave due in any day and if that dont give me good results I am going to ■■■■-can the DM and buy a Yuuksta.

Hoggy

It’s probably not the yoyo’s, or the bearing’s, fault. You might just need to work on your own skills.

Averaging times with having tons of variance like that in each trial isn’t going to give you a proper average. Tighten and loosen the string close to the yoyo to fix the tilt.

11

I admit I am not Yuuki Spencer, however there is NO skill involved on a dead drop.

12

No, there’s skill. On the bind before, you have to bind it tight so the dead drop has more string to wind with. And on the drop itself, you have to drop it straight and true. :smiley:

13

If there’s no skill involved, then how come I just timed a drop on my stock Lyn Fury and got over a minute several times, each followed by a bind?

14

Ok, all kidding aside, so either:
(a) I cant “dead drop” a yoyo, which I guess is completely possible.
or
(b) My DMII has “issues”, which I guess is completely possible.

and your thinking its me, I can accept that too, but its weird that every drop is consistently 8-10 seconds but you gave me food for thought. I will try to re-think my bind.

15

Got my ceramic Konkave last night. 2 minute sleeper without even trying and thats right out of the box (light oil as per dif-e)
So I got to work on skill/technique ( I am sure) or my DMII is somewhat out of whack (possible) or a little bit of both, LOL.

16

I got 10 secs for a dead drop using a YYJ Sunset Trajectory NXG.

Interesting.
What bearing and response?
