Why are champ eagles so opaque compared to other champ discs?
I am going to go out on a limb here and say, they are not any more or less.

Eric at the Factory Store told me over the phone when I asked him about it (I asked him about it because my CS Cheetah is pearly and opaque ). He told me that the clarity of the plastic is more than just the pellets they put in the hopper. There are a lot of factors that affect the finished product, just like how different PLHs can be from run to run.
I have heard that the weight additives are to blame but not sure how it all exactly works. I think its more about the actual "run" and seen opaque everything champion from innova I think at this point. "JL" is a fairly new term in that regard which was like the clear candy plastic but even that isn't really true anymore (the post I quoted is actually re:JL not being clear)

150g Hornets are clear, and max weights are opaque.

My 150g Champ Eagles are my clearest ones.

High speed drivers would need less weighting agent, I'd think. My Leopards are no more clear than my Eagles.

In honour of Blake's shame "Has DGCR peaked?". I present for you a necrobump of people mostly trying to bait our most beloved troll of years gone by. I think it's funny Noill is a Mod now...

I'll try to make this as understandable as I can....but this will get REAL sciencey, so bear with me please, or feel free to just skip this post entirely. Or better yet, go hit the end. After finishing up, I realized the first couple paragraphs aren't directly about "Why do I get more glide as it beats in"

Since we're talking about glide here, we'll treat the disc, as a whole, like a wing, or airfoil, as seen here.

Okay. When the disc flies through the air, you get a distinct seperation of air flow. Now consider two particles that get split up be the disc, one goes on top, one goes on the bottom. They will meet up again, behind the disc, so, because the top one has to travel farther, it is going faster. As speed increases, pressure decreases. You are left with a lower pressure area above the disc, and a higher pressure area below the disc. This phenomenon is called "LIFT" and for a given speed, will overcome the weight of the disc, and push it up. And what about that empty space under the disc? Well in that space, you get all sorts of forces, and I'm not totally sure what the net effect is...so...I'm not even gonna try.
When you now consider the rotation, think about relative speeds. For a RHBH, the left edge of the disc is moving faster than the right edge. So, due to the higher speed, the left edge will create MORE LIFT than the right side. This is shown in Fig. A below. The blue line is the amount of lift exterted on the disc. This is where you get the effect of flip, or HSS. The cant of the the disc then causes the overall lift force to steer the disc to the right.

AH! So why don't all my discs keep going right?
Well...you've got a rotating mass. This causes gyroscopic forces having to do with angular momentum and pitch and roll and whatnot. In a nutshell, the rotating mass of the disc causes a sum of forces call gyroscopic procession. This is what causes LSS, same as HSS, just the opposite direction. Fig. B shows the this force on the disc.
When you first release the disc, it has the most spin it ever will in that flight, and the assymetrical lift forces will outweigh precessional roll. But as the disc slows down, the lift forces aren't as large, and the disc rolls to the left.

It slows down, because of DRAG! Drag is a force that opposes your disc. The friction between the disc and air rob energy and the spin reduces, and the forward speed declines! BTW, a driver has less drag than a putter, due to putters having a blunt edge. So a driver's flight is therefore less lift-driven, and more ballistic. But don't think about that for now.

NOW, those of you still reading (god-bless you) are asking, "Okay, neat...what's this s#$t have to do with beating in and more glide?"
Well, turbulence is our friend here. A turbulent boundary layer on the surfaces of the disc eventually result in less drag! There's more fluid dynamics involved here, but trust me when I say, you end up with less drag. This is why golf balls are dimpled, but the reasons are a bit different for a sphere.
So, as you beat in a disc, it gets all these micro abrasions, that cause little eddies and vortexes that add up to turbulent, chaotic flow. In some cases, while this turbulence increases surface friction drag, the overall effect is a reduction in drag forces. This has to do with boundary layers, seperation points, and changes in pressure fields. But I'm damned tired.
The beating in reduces drag (to a point, then you start to get screwed again) allowing a disc to maintain the various lift forces for longer, lettings it go longer before fading, letting it glide longer.
Yeah. I think. Good Night.
Post #402... haha I've been looking for this for a while haha. At least I think this was the post...

Preube's post about not understanding the search function is priceless.

I’m a beginner. I Can’t throw understable discs. They always go right. I can crank overstable accurately. Help!

Throw neutral putters and mids. Like Aviar/Shark/Buzzz/etc. style discs, anything like that.

Throw as short as you need to in order for them not to burn right on you. Add power a little bit at a time.

Throw clean, not hard. Add power as you are able to, while staying clean.

Slow discs are good... sometimes discs that requires more arm means you will end up torquing them more to get extra spin. The Comet is also ideal for straight lines, slow armspeed also fast armspeed, training purposes and is great for playing with. See also Comet Love the thread.. I didn't believe it until I got one.. Then more...

Lower the left side of the disc down more when you throw it. It should come out of your hand leaning left and down, then it should stand up and maybe come back right before falling left. That's if you are a RHBH thower. I like hyper flipping most of my discs.
