Does the hole in the stem affect the dart?
Hi all!

I have used stems that have the hole in them for tightening them up and stems which don't have this hole.

I personally find that when I use the stems with the hole in they fly all over the place and i can barely keep the dart in a straight arc.

Does anyone else have this problem or notice the air effecting the dart due to the hole in the stem?

They never had that effect when I used them and I never heard of wacky flight patterns being due to the hole before.

To rule out your theory that the stem hole affects the flight of darts, try to patch up the pin hole with cotton or paper and see if there are any significant changes with it and without it.

Very interesting!

I'm glad I'm using pro grips. Guests cannot see images in the messages. Please register at the forum by clicking here to see images.

I always wonder the samething. Ive only used L-Shafts and I see alot of shafts from different brands and alot of them have holes...
Does it help the speed or accuracy or anything? Maybe balance? Ive also seen this ones that I guess resemble a golf ball... Whats up with those?

I like L-Shaft Carbons so far tho, Havent broken a single one....yet.

From a physics point of view, any contribution to the flight dynamics from the hole will be so small in comparison to the drag from the flight that it is insignificant. As to flying wonky with these shafts, my suspicion is that they are either bent, the base of the shaft is not sitting square to the barrel or the flight is eccentric to the shaft.

Their weight will change flight characteristics too. This thread has a great depiction from Harrows on how shafts affect trajectory. Heavier shafts will also highlight an inconsistent release more than lighter shafts.

I think if you send Saber all your metal stems he'll be happy to hammer them until the holes are closed up.

Absolutely not. The only thing the hole does is remind you that you aren't using a flight ejecting plastic (or nylon, whats the difference?) stem from hades. Look for the hole for ultimate flight griping satisfaction. Can't go wrong with a hole. Guests cannot see images in the messages. Please register at the forum by clicking here to see images.

C'mon guys we're just throwing small weighted objects at a target some 7-8 ft away launched from an infinitely variable and totally unstable launch pad, not deploying laser guided missiles.

I meant no offence to the above author at all what he's written I believe is spot on ....it's the topic itself, I'm afraid that holding the hole in a stem to such scrutiny is utterly futile.

There...rant over, that's my grump for the day Guests cannot see images in the messages. Please register at the forum by clicking here to see images.
