Disc Golf tips: Disc golf disc Basics – Understable? Overstable? Disc Golf Nerd


whatsup youtube this video is about understable
and overstable.  I am gonna teach you what those words mean and what those discs are
best suited for out there on the course.  So next time you are reaching for a disc to
throw a specific shot or looking for a new disc to put in the bag you can make a more
informed choice.  Im going to be showing you the numbers on newer run innova discs
and discs by other manufacturers.  I am also gonna explain the discraft numbers and give
you the basics on understable and overstable as well as some basic release angles like
hyzer and anhyzer.  So lets get started and just so we are on
the same page when we consider how these discs are going to react to being thrown we are
going to be talking about a right handed backhand throw.  Either a sidearm or a left handed
backhand would change the spin on the disc it would reverse it so all the things well
be talking about would basically be a mirror image so just to be on the same page we are
talking about a right handed backhand throw.  So on to the numbers.  Innova has started
putting these numbers on their newer run discs and other manufacturers have started to as
well so I will explain these numbers to you now.  So I have written down the numbers
for an aviar, valkyrie and an ape which is an overstable distance driver.  The first
number is just speed.  9 for the valk 2 for the aviar and 13 for the ape.  9 is pretty
fast definitely a driver.  2 is really slow definitely a putter and 13 is very fast there
are only a handful of discs over a 13 in speed.  So pretty self explanatory just the speed
of the disc.  The next number is Glide.  4 for the valk 3 for the aviar and 5 for the
ape.  Also pretty self explanatory its just how long the disc likes to keep spinning and
carrying down the fairway. 
Discs with high glide are great for beginners and really anyone looking to increase distance
because they just want to hang up in the air longer and keep traveling so that is good. 
3 is pretty nice for the aviar.  5 is very nice.  Anything 3 and up is good for glide
and anything in a 2 or a 1 means you are throwing the disc more than making it fly.   But
those kind of discs have their purpose too just so they are not gliding too far and so
they are more controllable.  All of these disc have pretty good glide.
The last 2 numbers are really whats determining the stability of the disc.
The 3rd number negative 2 for the valk and 0 for aviar and ape, is high speed turn.
So when you throw your disc backhand it comes out with some spin on it and it is picking
up speed that is the high speed portion of the flight. Right then as it reaches its natural
speed it should start turning to the right. Since it has a negative number in high speed
stability or high speed turn that means when you throw it fast it loses stability to go
straight and finish to the left like it would thrown slower and it turns to the right. Since
the aviar and the ape have a zero that means they should just fly straight during the high
speed portion of the flight and then finish to the left when they slow down.
The last number is fade which is how strong the disc will finish to left once it slows
down. So the valk even though it will turn it should also come back at the end and finish
left if you throw it correctly. The aviar having a one means it should just
go mostly straight and finish soft to the left it shouldnt really hook much at all.
The ape having a 4 means its very overstable so when it starts slowing down it should start
coming in to the left very hard 4 is very high for fade. If you have a zero for turn
the disc is going to be at least stable. And if it has a negative number it will be most
likely be at least somewhat understable. So let me show you the discraft numbers real
quick before we move on. They work on a scale of positve 3 to negative 3 This is a meteor
and it has a neg .5 with an arrow pointing to the right. Meaning it is understable and
wants to turn to the right. This drone has a large positive number 2.5 with an arrow
to the left meaning it is overstable. The force is the same thing it is overstable 2
with an arrow left. So those are the numbers for discraft not really talking about glide
or speed just stability. So what are these different types of discs
used for out on the course. First lets clarify a couple things. The opposite
side of the disc from where you are gripping it is called the wing. So consider that to
be a flat throw. Now if I tilt the wing down it will be on a hyzer angle.
So if it just a neutral straight flying disc a hyzer angle will cause it to go out and
hook to the left The opposite is an anhyzer which will cause
the disc to go from left to right. Now certain discs if you release them on anhyzer
will produce what is called a turnover shot where it will turn to the right and never
come back. If you throw it pretty flat and not too hard it will turn over during the
high speed portion and then come back producing an S curve shot. Another shot you use an understable
disc for is sometimes a disc is so understable you can just throw it flat and get it to go
left to right just based on its natural turn you don’t even need to give it the angle
what I like to do with understable discs most of the time is I like to throw them on a hyzer
angle, so rather than throwing it flat and having it turn to the right the turn actually
causes it to pop up straight and then fly like a stable disc from there. So I like to
throw on hyzer it feels more natural, and it comes out and maybe turns a little bit
and then comes back to the left so you get more distance that way and if you control
the angle you can get a very straight shot all the way. You can also use an understable
disc for a roller shot where you give it such a hard anyhyzer angle that it lands on the
edge and rolls down the fairway. A very fun shot when you get the hang of it but they
are tough to control so I don’t throw a lot of rollers
Finally you want to throw understable for tailwind because with the wind at your back
it will push the disc down and to the left making the disc fly more stable and finish
stronger to the left than normal. Now overstable discs are good are good for
headwind because headwind actually makes the disc less stable so you can throw an over
stable disc into the wind and have it fly like a stable or understable disc. Also for
sidearm. People generally use overstable discs for sidearm because it generates a lot of
speed and torque on the disc and overstable discs handle that speed and torque better.
Also for overhead shots like tomahawks or thumbers. And also hyzer shots where rather
than giving the angle you can just throw it with a little hyzer or even flat and it will
naturally go out and hook left due to the stability. And if you release them with an
anhyzer angle you can force them to go right for a period of time and then they will fight
back left producing an S curve shot which helps with adding distance and navigating
certain fairways. A stable disc would be something like a buzz.
Something where its not really overstable where it hooks left and its not really turning
much either. Its really just holding the angle you release it on. So a lot of people like
to use stable discs most of the time and just give them the angle they want them to fly.
I like to throw on a hyzer so I like to throw somewhat undesrstable discs so they flip up
straight. Now there are some factors that change the
way discs are meant to fly. So sometimes the numbers can be confusing because you try a
disc and its not flying how you expected it to based on the numbers
I wanted to go over those factors now. The first is plastic type. Different plastics
have difference flight characteristics. These are both buzzes but this one is in elite x
so its more understable and this one is in FLX plastic so it is more stable and it doesn’t
turn at all so even though they are the same type of disc they fly differently based on
plastic. Another factor is the shape of the flight plate. You can see the flx buzz has
a flat top and this one is more rounded on top or dome shaped. Generally discs with flatter
tops will be more overstable and discs with rounded tops will be more understable. The
exception being certain high speed drivers the dome shaped ones are more stable. But
generally flatter is more stable. The other factor is weight even thought these are both
soft magnets, this one is heavier than this one so it is more stable. The heavier disc
will finish harder left and handle the wind better and this one will turn more. Finally
there is just condition. This one is more beat up and used than this one so it is less
stable even though they are the same weight and plastic. The blue one is more fresh so
it is more stable. So there it is, lots of information to throw out there for you guys.
I wanted to keep it kinda short but it is a lot to talk about. If you have any questions
about this or any other disc golf related topic as always you can leave a comment or
send me a message and Ill get back to you. Thanks for watching. Cheers

    There are some people who think the colors of discrafts Z plastic do have distinct flight characteristics and some who think its ridiculous. I have heard that Pink Z discs are usually more stable but I dont throw Z plastic much at all and can't confirm one way or 'the other. Sorry I cant help more. I would like to try a nuke ss they seem fun.

  • Thank you so much for making this video, it has helped me understand a lot more so I know which discs I want to buy and also what throws I should use with the corresponding discs I already have

  • Great, Glad I could help. Thanks for watching

  • Just realizing now you said left hand backhand. An SS thrown flat should probably turn left for you as a lefty. If it doesnt turn enough thrown flat try giving it a little anhyzer angle. Sorry I misread your comment. cheers

  • Best explanation I've seen or read. Thanks.

  • Wow thanks very much, thanks for watching.

  • Yes the last 2 numbers are what you use to determine a discs stability. As for your other question I recommend you click the annotation at the end of this video and watch my Video on Percieved stability. I think it should help. Thanks for watching, cheers

  • excellent, glad to help. Thanks for watching

  • ok, let me see if i got this correct. stable = strait over stable = left under stable = right?

  • Yep sounds good

  • I am a newcomer recommendation for the best discs out there

  • I have a video about getting started you can find on my channel if you like. I suggest you start with a putter at first to learn the basics. However if you choose to go with a mid range or driver good beginner discs will be understable. I also recommend you stay away from fast overstable discs for a little while until you learn how to throw. Hope that helps.

  • Great vid. Have you tried any Vibram discs yet? I love my new ibex.

  • Thanks, I had a summit for a little while but I didnt like it that much. I would like to try the drivers and midranges they realeased but they are pretty spendy and I am hooked on Discraft these days. Cheers

  • all those numbers do not matter as much as you would think there are a lot of things that effect how the disc will fly including windspeed/direction, weight, grip, and not to mention every person has a different way of throwing as far as strength and style. Something that effects flight believe it or not is color, I work in the plastics industry and believe me the dye added to the plastic greatly effects the dynamics of the material. Go ahead and try two discs same weight and different color.

  • Try Lattitude 64 or West Side if you want premium discs they are indeed the best out there.

  • As a newcomer to the game, I just wanted to say thanks for posting these tips and reviews videos. They've helped out quite a bit with getting started.

  • I am very glad to help so you are very welcome. Thank you for your support and for your views. Feel free to contact me any time if you have any disc golf questions. Cheers

  • very usefull thank you!!!!

  • thank you for watching, cheers

  • Great video. Thanks.

  • thank you

  • That aviar appears to have a bump in the center, what is that for?

  • That is a night ize "hole in one" LED module that I have installed in the disc. It has a nice led in it for night golf. Im actually looking to trade or sell that aviar at the moment if anyone is interested.

  • btw's 13 is the highest speed disc there is

  • the legacy cannon, rampage, and the Westside King are all 14 speed

  • Can you recommend any good understable drivers for with players without huge arms?

  • For players**

  • Sure, I like the FLX Surge SS quite a bit from discraft, also 150 class pro D forces are easy to throw and get good distance. You also might like the Avenger SS or slower discs like the XL. Also a meteor is a nice disc for mid range shots that can and should be used off the tee on shorter holes. For Innova, discs like the Roadrunner, Sidewinder, Valkyrie, Leopard are all pretty understable and easy to throw.

  • Okay, thanks ya very much.

  • What does "turnover" mean?

  • A turnover is when you make a disc turn and not come back, for a right hand back hand it would turn to the right and hold the turn all the way.

  • Thanks, I never would have guessed the meaning.

  • Does a higher speed mean you have to throw the disc harder to get the disc to perform its flight pattern? So if a beginner had a speed 13 disc he wouldn't be able to use it correctly because he cant throw that hard yet?

  • Yes you need to be able to throw the disc up to its natural speed in order to get the intended flight path out of it. I highly recommend checking out my video on Perceived stability for more information on this. You can follow the link I annotate to at the end of this video or just search perceived stability. Thanks for watching

  • Christopher Dantonio

    Love the Victory HopDevil Disc!! You from Philly?

  • Disc Golf Nerd

    im from NY but live in Oregon. That was one of the best discs I had but I lost it and never got a call about it.

  • Christopher Dantonio

    I grew up about 15 minutes away from where Victory is brewed and still live close so we know that beer very well! Great videos!! Helped me a ton!!

  • Disc Golf Nerd

    great glad I could help you out. Thanks for watching

  • Where in Oregon? 😮

  • Portland

  • How about this? My FD Jackal has stats of 7 6 -1 1 and it goes heavily to right. And my Leopard is 6 5 -2 1 which should go even more to right, just goes straight. How come? Can you help with this please? So confused 😀

  • Well some discs are just more or less stable than others even if you have two copies of the same model of disc they may fly quite differently. The flight numbers are just a guideline really. Until you throw a disc you cant really know exactly how It will fly. Small differences in the plastic shape and density will change the flight from disc to disc. Hope that helps.

  • i have an under stable disc but it still turns left. is that normal or is it the way i throw?

  • Good video, helped me understand the terminology used in disc golf. Thanks.

  • This video helped me a lot, going to go buy the right disc for me. Thanks for posting!

  • Great video. I watched a video of someone else trying to explain some of the same things and they didn't do half as good of a job conveying what the numbers actually meant. Loved that badass Hop Devil disc and hope it works as good as the beer tastes. Keep up the good work!

  • what is with that nipple in the middle of your aviar?

  • Very informative. Thanks dude!

  • latitude 64 came out with a speed 15 recently. over kill much. haha.

  • Thanks man helped me a lot

  • Great vid, what fps was this filmed in?

  • So, Being a Lefty, If I throw Side arm, Will that then perform the same as a Righty Backhand? 

    and If I want an Understable disc, Should I buy a technically overstable?

  • Is it the Turn number, Fade number or both that determine whether the disc is over or understable?

  • Nicklas Karlsson

    A small comment on the speed (3:30). Once the disc is released from your hand, the laws of physics state that it can only slow down due to air resistance etc, it can't "pick up speed"

  • Great video

  • I'd be happy to buy a nerd stamped disc. Let me know how.

  • I’ll take an Air Trespass if they’re not all spoken for. Thanks! Scott

  • Brandon Bunting

    awesome info… thanks for the video

  • Disc ' Speed ' ? Do you mean speed of travel from point A to B ? Or do you mean rotation speed of the disc ?

  • Kory Kirkegaard

    Thanks for his and your other videos man!
