negative angle of attack

post #1 of 12
Thread Starter 

so today went to see my launch numbers and was suprised on what was found

 

SS 116 ave high 122 low 113

 

ball speed  165 ave high 180 low 148

 

launch angle 7.5 ave 13 high 2 low

 

come to find out i have a neg AoA of - 7

 

ball spin was from 1710 to 2746

 

hitting 3 drivers

 

alpha 9.5/ aldila nvs 65

bang springboard 9.5/ aldila nvs 85 pink

exotics 10.5/ aldila nv 65

all shafts are stiff

best drives were with the bang head combo

 

 

need some drills to create a positive AoA

Put the ball farther up in your stance and tee it up higher.

 

You want to hit it more in the up swing, so naturally that means moving the ball forward and up....i am very suprised that you are hitting the ball with such little spin with that launch angle tho, doesnt really sound right.

I thought the same thing. With an AoA that negative and that high a clubhead speed, you'd think the spin rate would be much much higher.

Agreed.  -7 is super steep for a driver and those spin numbers are way low (not bad low, just seemingly too low for that AoA).  Considering your AoA in conjunction with your swing speed, I'd expect you to be ballooning the sh&t out of balls with a stiff shaft.

Is it possible you misread the monitor, and your actual angle of attack is -.7 degrees?  That would make a lot more sense.  As others have stated, it's almost impossible to get those low spin rates with a huge angle like 7 degrees.

i wish the ball had a slight ballon effect when i hit it

its like rocket taking off but dies and falls to the earth like a rock

the height of my ball is only 30yds high but it does travel

what else had him puzzled was i was hitting straight or with a slight draw and in the center of the club

 

what my swing coach was saying i might be coming over the top slightly

 

because my club at the top of my swing  is inbetween my shoulder and neck causing a steep attack on the ball

 

ill try and post a few swings fri and see if you can see whats going on

the ball is teed up 3" already (i use 3 3/4" tees) and when my swing is over the tee is only about 2" high so i know im pushing the tee into the ground

as far as teeing it farther up its allready on my right toe

Keep th enegative angle of attack, positive angle of attack is a myth.. most pro's have a negative angle of attack for all clubs.. only the ladies tour do pro's have positive angle of attacks for the driver..

 

All those numbers were really good, i would keep them..

 most pga golfers are around like -2 to 1...but hitting down on a drive so much that your AoA is -7 is very extreme.  i would check those numbers again, tho before you think of changing anything.

yeah -7 is to much, check your alignment.. you might be placing the ball to far back in your stance... post a video of your swing

Launch monitor numbers can be off so far they mean nothing.

 

Launch angle ranging form 13 degree to 2 degrees?  These can't be center hits.  116 SS with under 3K spin at -7*!?  Not likely.

 

I would say the monitor you were using is about as useless a t's on a bull.
