i just got 4 new z-buzzes. are have slight dome, except one. it is a 167, and the others 171 or higher. the 167 has anti-dome. it is concave on top. how will this one fly compared to the others? should i use hot water, etc., and try and get the dome back to normal, or at least flat?

I love the Z-Buzzz so I have a bit of experience with them. For mine, it has always seemed that the less dome it had, the less stable it flew. So the concave one you have there would be your most flippy, and the domey ones would be more stable. That is just my experience though, and I'm not a huge fan of "domed" discs, so yours may vary.

As for getting it back to the original shape, I would think whether you want to do that or not depends on whether it flies the way you want it to. Throw it some and see how it does. I have a DX Aviar with a completely sunken in top that is money for straight and turnover approaches.

I have heard some people say that boiling a disc is illegal, but according to this

C. Players may not make post-production modification of discs which alter their original flight characteristics. This rule does not forbid inevitable wear and tear from usage during play or the moderate sanding of discs to smooth molding imperfections or scrape marks. Discs excessively sanded or painted with a material of detectable thickness are illegal. See sections 802.01 D, E and F.

it should be fine, as you're returning it to how it originally should have been.

The disc that the PDGA sent me with my membership was a Discraft Stratus and one half of it is taco'd/caved in big time. I never really planned on throwing it but it really looks like a piece of garbage so I can't even admire it :p

I feel like it sat under the wheel of an office chair for a year before it got sent to me. Actually...I'll just take a picture.

It's kind of hard to tell since it's black...but the right side is very concave.

Does Discraft stamp their rejects for the PDGA assuming people aren't going to throw the disc they receive?

They don't really even make the Stratus in ESP plastic, it's just a PDGA member disc thing, so I don't think that'd be the case.

Nope. Discraft's quality control is second to none. Any type of concave flight plate or office chair depressions happen during shipping. In my experiences with PDGA sent discs, they come in a thin bag with absolutely no protection :mad:, and are at the mercy of your US government employed mailman.....who's always on the verge of going postal. :D

mine were shipped from a reputable retailer but were "suctioned" together, and one of the 4 buzzes (all new stamp) was totally and deeply concaved. It was 10 grams lighter than the others, maybe that, combined with the fact that it was suctioned onto another disc, and i had to forcefully pry them apart, was what happened. I gave it a day: still concaved. safe to say through the use of circular objects, boiling water and freezing temps, it has a nice dome. I think this is why innova puts that little white sticker on the rims of their discs.
anyway-do others agree with the assumption that the domey ones are more stable, and flatter ones less?
thanks

Thanks for clearing that up. I assumed that is what happened. I didn't mean for it to come out like Discraft was responsible for it, but more like if people are going to get a disc to admire, why not just stamp the rejects to save money? I have a few Discraft discs and they're all perfect. I love my FLX Buzzz ;)

Since I haven't thrown my concave disc I can't say for sure. Out of curiosity I've studied all of my discs to try to figure out what gives them their flight characteristics.

The most overstable disc I have is a Star Max and the flight plate is essentially flat, no dome to it at all.

My most understable discs are a DX Kite and DX Archangel. Both have extremely domey flight plates. However, I assume that the flight plate acts more as the part responsible for glide. As the air passes over the rim it creates a low pressure zone inside the disc. The larger the dome, essentially, the larger the pocket for the low pressure, which means more for glide than stability, as far as I can tell.

Again, these are just my assumptions from looking at the discs and understanding their flights. I could be totally wrong.

The best way to find out is to just get out there and throw.

I hear that's why Innova has those small white stickers on the underside of the rim, to prevent the discs from suctioning together. Not sure if that's the reason though.

I agree: the flat ones are less stable than the domey ones (in Z plastic.) In other plastics I don't know. I have an incredibly flat FLX 173 and it's WAY more overstable than my other buzzzes.

Side note: I also got a warped stratus from the PDGA. I doubt I would throw a disc that's that understable out of the box anyway. But this thing is just ridiculous. Threw it once and put it in storage. I assumed they got some good bulk deal on slightly messed up plastic. Maybe not.

FizzyP, hang on to that warped understable Stratus. When you're 50 or 75 ratings points higher, you'll have a use for understable plastic!

That has been my experience as well both with ESP & Z. The more domey the more over-stable.
I've never encountered a domey FLX.

Slight dome = straight.

Flat to concave = flippy.

I know a couple 1000 rated discrafters that rock the stratus.

yea--the new dome made it much more stable.

I can back everything up that has been said on this thread, however the difference b/w the domey and flat Buzz can be a little more complicated. I have always liked keeping a stable/overstable Buzz along with one that has like a -1/2 in HSS so it flies straight at lower speeds. I definetely prefer flat ones for my straight Buzz as they can fly truer on their line for as close to their whole flight as any other disc besides putters. I used to keep a domier one as my overstable Buzz b/c in calm conditions they get a lot more fade at the end of the flight. The problem was wind. It seemed that the domey Buzz, although more overstable in calm conditions, flips as much or more in the wind than my flat Buzz, and gets lifted and played with much more. So now I carry 2 flats.

cool--that's what i am doing as well. the flat ones are pretty incredible. I am happy with my switch to them.

I have been using a Crystal buzz and in my exp they are all pretty flat which I like! I just never got used to a Z Buzz :(
