Ball Flight Question

[Brian Manzella]

"andrewwrx":

"The question he was going to post was as follows. The old ball flight
rules suggested a club face that was square to target with an in to
out swing path would result in a draw that set out right and came back
but the new laws say it would set out straight and ten draw right of
target, is that correct?"

The answer is NO.

And the "new ball flight laws" has a name—the D Plane.

I'll give you a couple of scenarios...

1. Driver, 11.25° of dynamic loft, 0° square clubface, resultant club path of 8° inside-out.

Ball will START ~ 9 yards to the right and curve back to the left.

Why?

Well the path is aligned 35 yards to the right at 250 yards, and well the ball will start about 85% to the clubface normal, but that is on a 11.25° tilted D-Plane.

You get it?

2. 6 iron, 22.50° of dynamic loft, 0° square clubface, resultant club path of 8° inside-out.

The 85% changes to about 75% the yardage changes to about 170, etc, etc...

The ball starts about 12.5 yards to the right....

Whew....

Brian,

With these scenarios would the ball end to the left of the target?

Thanks

The ball would end up well left of the target. In order for the ball to finish at the target the clubface would have to be half of the resulant path. In both of those cases the face would need to be 4 degrees open to the target.

That's why I tell people that if they can understand D-Plane, golf immediately becomes easier and much more logical. Won't turn a 10 handicap to a scratch, but points them in the right direction.

Consistency for the cover shot...

Does D-Plane have a Hyphen?
Or is it D Plane......
Just because the tiny little snowball we are looking at right now is being packed firmly by those here to see it.
Soon it will be a monster of rocks and ice careering down the slopes of golf and will smash into the town below....
I have systematically been asking all kinds of golf people if they know what it is, and I have hardly come across anyone who gets has even hear of it, let alone gets it. Big deal from a big club called me today asking a question, I probed, no clue.....
I vote for a hyphen. Perhaps not gramatically perfect, but it looks nice to me.
THE BIG QUESTION IS... when does The D-PLane make the cover of Golf Digest...?
Has it even been mentioned in that publication yet?

My ADHD kicked in on dynamic loft. I need the remedial class

Won't be a big spread in any magazine that has a top 100 type list. Cause those guys didn't know it for too long.

I suspect the opposite will happen. As the D-plane becomes more well-known, I can see the future issue of Golf Digest where one of the top staff instructors will "discover" the concept under a different name.

 

[savydan]

Can't. You can fool non-scientists that way, but not real ones. You can't pretend it wasn't discovered when it was.

This ain't someone's pet name like X-factor.

Is D-Plane knowledge analogous to mathematics where it is merely a simplification of teaching that expresses the same thing in other terms, or is it indeed new knowledge?

 

[andrewwrx]

Sorry, that was me, I meant set out straight and then head well left of target......(typo on the "right")

However, it appears that my original thinking was right and that square face, in to out path results in a draw......

I think.

Thanks

This is so true as right now most golfers are using old laws.

I went through every book and magazine I have this weekend to find out how how they say to hit a Draw/Fade and everyone of them says aim club face at target and align your body to left or right and swing along your body / toe line, the club will start on your body path line and curve back to your club face target line.

But if I understand the Dplane stuff on this site then that old method is wrong and if you set up that way the ball will start somewhere between target and path and end up further left/right of your desired target than you would expect based on the old laws?

Does this make sense or am I still missing the point.

Sorry if its obvious to some of you, but as said above if golfers really understand this point it will be a significant help.

Cheers

 

[mjstrong]

DeepRedCee - yes, your understanding is correct.

Like I've said before, it easily explains why I could hit the amount of draw I wanted just by feel, but when I had to manufacture a fade, and followed the wrong instructional info, I always hit push fades that started too far right, and ended up too far right.

DAH.........

I don't know if it's my hard Italian head but in "Concept" I understand the D-Plane, but I'm having difficulty picking up the math and were those numbers come from.

I'm not interested in being a zero handicap, but I would like to have the knowledge understood so I'm working on the right things.

Am I alone or are there others who can't seem to get it!

Sorry if I have slowed down this thread. But I really want to learn it seems as a reasonably intelligent person I should be able to get this. Or at 52 is my mind beyond comprehending this concept.

Thanks

no, it'd probably be a hook.
