Haha. I should start signing my email. "2x Austin Distance Champion"

My best throw was 467m, and I had a 452m and 440m throw. I also had another that felt like a good throw that I think might have broken the record, but I didn't locate (didn't realize I missed it until I got home). I'll link the video when it finishes.

In other news, Alan aparently broke the long standing footbow record from the 70's this last weekend!

That's amazing! I haven't had a chance yet to get into the website and (try to) update your distance throw with the details you sent me. We'll need to get this one posted there too.

I've been looking out my window trying to imagine a 467m throw. That's sooo many streets over! The fact that you're using that style of sling honestly warms my heart.

I'll join you next year for sure! Maybe we can brainstorm on some easier ways to find landing zones.

I'm curious what release speed your simulator said. I would guess my release angle to be about 35-37 degrees.

@Rhonan Your sling design is still the best distance sling I've used!

@erricrice Bonneville sucks, but Austin is amazing. They are actually really easy to spot @ Smith creek (relative to bonneville).

Also, I'd say get rid of the tails. It's a gimmick. You don't need 'em.

I'm curious what release speed your simulator said. I would guess my release angle to be about 35-37 degrees.

I do not have simulation data of biconical projectiles. So the input for my calculator is based on simulation data of a 50 g leaden ellipsoid with an aspect ratio of 2.2/1. For the air density I estimated about 1.0 kg/square m (1800 m above sea level, 25°C).

The calculator says:
- 74.5 m/s when the angle of attack stays under 10° (projectile orientation is following the trajectory)

- 76 m/s when the projectile is heavily overstabilized and does not change its orientation throughout the hole flight path

airtime:

- 9.0 s

- 9.8 s

I think the real release speed (for the red option) might be a little higher than calculated, because in reality, even with a perfect release, the projectile will do its precession movement which means that it is also pointing left and right at times and that will cost a little bit of energy.

Ok, my 'simulations' also suggest mid 70's as the likely velocity. But I'm fairly confident that my best throws were about 80m/s. No way of really knowing though. My chronograph doesn't want to work anymore.

I wish there were a way to measure and quantify wobble. Getting rid of wobble really seems to be the key to distance.

I have been trying to pause and slow down the video to get a closer look at the slings you were using.

Is there any chance you might show us a few photos?
I'm really interested in the dimensions, adaptations and design choices you made for those slings.

I have a few new ideas of my own now that I'm making slings again.

My friend, I just copied your sling almost exactly and made it longer.
The only 2 differences were that I didn't tighten this one like you did (the 50" (127cm), red one). and the pouch had additional strands added so it was 5 strand braid per side instead of 3 per side. It was a pretty floppy sling, but it still worked.

I used another sling for the tailed glandes, and it was only 43.5" (110cm), but tightened like yours. It probably would have been great, but was just too short. Took me ages to finish that sling. Wish I would have made it longer.

I'm hoping close proximity to IG will turn my bad distance throwing into slightly less bad Grin

Come join us in the middle of nowhere!

We'll have lots of fun distance ammo, and I'll be bringing my new oval golf balls too - a bit light so they probably won't work for massive distances, but overall they throw pretty good!
