Ah ya, that's why golf balls hook to the right so badly. Ratman says he can achieve backspin but I've not the skill for that yet.

Yeah if you have enough spin on it, and i can get a pretty strong left hook on a tennis ball/rock.

anti clockwise surely.

It is controllable - toa certain extant. I can sling golfballs at right angles to the left . With a little concentration I can curve them to the right as well.
Getting a perfect backspin is probably harder with a sling than with a golf club.

But if you can do it golf balls go one helluva long way.

The spin is also why glande shaped missiles fly straight

The best way to throw is spiral, you have better accuracy-power.
I believe we could get better distances with backspin but it would be very difficult to adjust release angle since you should change with every stone or wind.Also i don't understand if the drag raises a lot with backspin making it useless.

When i was a begginer at slinging i threw backspin all the time i remember two awesome throws :

1.throwing a stone, fig-8, release angle very close to 0 it flied parallel to the ground for 70m then it went up 1m for 5m and the it fell down almost vertically

2.throwing an orange,fig 8,I was standing below electric wires (those that are low 7-10m used in the cities) i threw backspin parallel to the wires ,the orange lifted till it touched a wire it continiued for almost 10m touching the wire and then the orange split in half.

below is a picture of the hop up used in airsoft .i don't remember where i found this picture.

Except from magnus effect there is the angle of attack that javeliners use for distance i believe we can apply it to spiral throw but as i said above for the magnus the same goes here, it might raise the drag making it useless.

here is a pic

Magnificent ! But isn't that clockwise ? (and hence pulls to right ?)

I am not knowledgeable on physics and of the sort. But what exactly is the technique on how to put a backspin on a sling throw?
