Ask Dave Dunipace About Innova Discs

[prairie_dawg]

Cantrell - CHING has completed the first final mold in a new series that features a complex contoured surface. We expect to begin shipping this summer. Small dimples may not alter the flight + or -, however strategically placed larger 'thumb bunkers' can direct performance of a spinning disc...although ergonomics is the most obvious benefit.

And I thought when I was doing that to my ss putters I was being original

Wasn't this the main idea behind the Wham-O frisbee "flight rings" (a.k.a. "lines of Headrick") on the outer part of the top, still to be seen on their new line of golf discs, "Touchline"?

Yes. In theory at least, the Lines of Headrick act as vortex generators, reducing the drag caused when air flowing over the disc suddenly breaks over the outer edges leaving a low-pressure pocket trailing behind. The microvortices generated by the Lines stabilize the flight pattern, allowing the disc to fly farther. (For an overview of disc physics, see Louis A. Bloomfield, "Flight of the Frisbee," Scientific American, April 1999. Note, however, that physicist Michael Gold, in an essay entitled "The Fairy Tale Physics of Frisbees," cautions that the efficacy of the Lines has never been scientifically demonstrated.)

Felix, whenever I see that you've posted, I read it. I almost always learn something.

You mean the "grip rings" on the inside of the rim ! I have a #2 Flyer (I think), the rings were really painful if your using the powergrip, after a few throws it went up on the "discwall" instead. One of the worst discs a bought.

PS I think I´ve to edit my post on the thread "Worst disc you ever bought"

[mf100forever]

The Dimple were made in two versions by Destiny/dynamic Disc (Jan Sobel), original and CDS.

I saw a new KC Pro Roc yesterday that didn't have 11x World Champion mumbojumbo written around the circular ring on the stamp. Is this a new KC Roc? And since Ken Climo didn't win the worlds in 2003 there is no 12x????
That would make sence to me, just wondering if that is what is going to happen. And if these discs are the same as the 11x mold.
Cheers,
Matt

I never got an answer....thought I would post it again...thanks

Yes to first two questions but not sure if the new ones fly like the 11x.

Dave, I have noticed that the champion plastic is a little different from disc to disc. For example, monsters are almost always an opaque, rubbery plastic. Banshees are opaque and clear, but always hard. Orcs are clearish-opaque and pretty hard as well...Do you guys do this to manipulate flight, or is there another reason? Do you test different molds in different champion variations? Thanks.

[davei]

discspeed, different discs require different plastic combinations to run effectively, and in the weights demanded. Banshees can run down into the 140 gm range, and a Monster wont run below the 160s for example. Lighter plastics are more flexible generally, and a mix is used to determine weights.

[mikeP]

Is there anything special about blue candy plastic that makes it more overstable? I have heard others talk about this before, and in my limited experience I have found evidence. For example I have a blue champion panther, a red one, and a green. They all weigh the same on a scale (173g). The blue and red are like different discs with the blue flying almost Roc stable, and the red like a stingray. The green is in between. I also have a red and a blue Viking (both 173g), which also fly like different discs (blue much more stable). I am just curious as to if this is a fluke, or something I should consider when buying new plastic. Thanks again.

[davei]

discspeed, I think it is a fluke. But, having said that, I wouldnt be too surprised if there were something to it on a limited basis. Nothing I am aware of though. You could ask others on the message board if they have noticed this phenomenon. That might be useful.

Dave, are there any plans to release a 20th anniversary Aviar -- perhaps in candy or as a CFR?

[rob]

Oooohhh, Champion Glow Aviar? Dave, could it happen?

[mf100forever]

Beadless!!!!!!!!!!!!!!!!!!!!!!!!

[jaymo]

Dave, I have some aviar questions... I really tried to look for a good thread, but I couldn't find one that really addressed the issue I am considering... the "height" of the disc...

Basically, I know the difference b/w Big, Small, and No Beads but there seems to be a difference b/w the height of the disc... I have 4 different aviar molds (including the omega) The KC pro (11x) seems to be the slenderest. The regular P&A seems to have the same mold as both my Q and supersoft plastic omegas, with the small bead... and then there is my Champion Aviar (new champion plastic) which has a big bead, but is very domey (unlike the other big bead KC disc)... so my question to you is, how many different molds are there? or am I totally whacked?

thanks in advance...

Ohh yeah and P.S. how's that SE Orc coming???

[davei]

Robj, good idea. Hadn't really thought about it, but I like it. Thanks.

[davei]

jaymo, we have two complete Aviar molds and an additional part. We usually only use two combinations that make either putter type or driver type. Most of the variation that you are talking about comes from plasitic and molding, rather than mold types. However, the Champion is a putter mold with a big bead.

Oooohhh, Champion Glow Aviar? Dave, could it happen?

BIG BEAD!!!!!!

[prairie_dawg]

Dave,

When did the JK aviar first come out and was it a big bead or what version?

Thanks in advance,
Ray

[davei]

Ray, the JK Aviar X came out about three years ago. It is a big bead driver type Aviar.

I would like some JK Aviar X's in Glow plastic
Or Candy Glow JK Aviar X's.
Sorry about that Dave, I'm still on medication [img]/msgboard/images/graemlins/smirk.gif[/img]

[rhett]

I thought the JK and KC Avairs were the same mold, Big bead. Just different plastic.

Is that right Dave?

Correct, although champion aviars that bear KC's name have been run in big and small beads.

Robj, good idea. Hadn't really thought about it, but I like it. Thanks.

It is such a sweet disc; paying tribute to it on its 20th anniversary seems appropriate

Don, you sound quite lucid to me

C'mon Rob.........you just never know........

I just may have one Bronzed !!!!!

Anything with JK Aviar-x in the title sounds great to me. I like the idea of a glow JK Aviar-x only tournament.

[browntrout]

Dave,

I don’t want to sound like a total dumb[*****], this being my first post and question. I guess this is more of a request. The Teebird is one of the best discs ever made. I am of the opinion the ROC, Eagle, and Teebird are the best discs ever made! To this end the 10X KC versions were some of the best made. Given the advancements in both manufacturing and plastic technology. Why can’t these disc be remade?
