Default Applying Flight Testing to Ultimate Discs

I’m a part of the disc standards test group with USA Ultimate and I believe that flight charrsrisctics are a vital statistic that is missing from the certification process.

Although Ultimate discs are inherently low speed disc, why couldn’t the same methodology be applied to determine flight characteristics ? Manufacturers don’t test them as really they are supposed to be consistent and Beth team discs. But they probably have numbers just like a zephyr or similar throw and catch discs does.

I think having some imperial days to help back up the decisions as to what discs are recreational or championship level, you need some data.

Could you not get a pro group of ultimate players to test like a manufacturer of third party and determine the flight characteristsics of each disc?

Ultrastars, Wham-Os, and Pulsars all fly different.

Wham-O's don't count. What about the Aviator? Apple?

By "every ultimate disc ever," we all know he meant Ultrastar.

I'd say 2/7/-2/0, but that's me.

As for the original post, no manufacturer has ever done any flight testing beyond (at most) throwing prototypes. Empirical data is irrelevant. If you figure out a way to standardize measurements and flight numbers, that could probably translate to disc golf and might be useful. Go for it!

It might be more useful to create a modified flight rating for ultimate discs that considers only glide and turn? I haven't thrown enough recently to know how the new molds differ from Ultrastars. Speed and Fade strike me as being slightly less relevant for ultimate. Maybe add something for wind or for hammers?

Edit: that would be the way to do it, and better than in DG.

I would never dream of applying flight numbers because the variation between ultimate discs is so much smaller and the applications so varied, but a matrix of relative performance between ultimate molds would be useful. Stuff like plastic comfort, high & low-speed stability, glide, degree of IO required to pull successfully...

There are definitely differences in Ultimate discs.
On my last test discs sent to me from USAU, one was a similar mold to the ultrawtwr but was much easier to throw inside out RHFH. My son gained 20uds on his I/O flick and had improved spin.

Your right on the money m, the flight chawvyrttics are less since it’s a low soeee disc. I think some flight testing would help generate more competition from manufacturers and get more people playing ultimate.

Thanks!

DG.
So since the disc is low speed, do you think that makes flight testing easier or harder?

Since it’s supposed to be a “Neutral” Disc could you say,

0. Throw disc at 50% power at 20 & 40 yd. distance to do one set each yo stationary and moving receiver, record turn and fade for disc for each release style.
1. Flat,
2. Hyzer (outside in) 25%
3. Anhyzer (inside out) 25%
4. Record the fade of the angle as distance approximation (inched, feet) and percentage.
(e.g. 10% Fade)


Ultimate discs can be thrown by top level players up to 120yds. They can be thrown with touch at half that distance easily by most club players. Seems like the are inherent characteristics of basic flight could be recorded and used to stimulate the marketplace for recreational & competitive discs.

Inbounds used to say they had like 13 tests. Are there lists of test criteria from manufacturers or 3rd party people?

Thanks
