canopy for airborne acro? (not swooping)

Recommended Posts

I put 100 swoops on a stiletto 120 a few years ago, and about 30 on a Stiletto 150. the 150 was too slow in roll and 120 still was too ground hungry for what I want to be doing. is a Diablo better? faster roll?

Thanks for the help, I know its a weird thing to be looking for. I love flying my bullet but freefall jumping it wears it out exponentially faster.

How does that work? Slider, RDS, or sew on a bridle attachment point?

Where do people discuss this sort of thing?
It isn't the usual thing on dz.com. ParaglidingForum.com? Or is there a site that speedflyer canopy pilots congregate at?

I know of the small acro paragliders but not what's been done with speedflying wings.

A Diablo will turn like a top but has no glide whatsoever.

Why would you want glide?

Another *fast* turning canopy would be the Vengeance, but it's groundhungry as well.

I am. I think.

I don't expect it to be to long a wait before someone builds a strong enough glider... I just hope that I'll be young enough to still jump and fly it [Fingers Crossed].


A jumpable Bobcat would be a great start.

I think it should go the other way... I think we should ask Ozone or Gin to build one of their gliders from heavy ZP and not light sail fabric. i don't care about pack volume.

I have jumped a few gliders now, the flight performances are black and white compared to parachutes.

what would KICK ASS is a long wingsuit flight through clouds, and then opening a Bullet 16 or bobcat at 5000' and whipping the thing around for another few minutes. easily doable. I have jumped my gliders, just not for wingsuit...

I’ve a put a couple hundred jumps on a Diablo 135 choosing it over a Stiletto at the time as this was nine years ago. It is a blast to fly with a super fast turn rate and fantastic openings. More fun to fly than the Stilleto IMO for the time and what I was looking for. That’s what you get out of a 7 cell, boxed shaped elliptical canopy. It doesn’t have the flattest glide rate and you’re not going get a whole lot of swoop out of it. I enjoyed it quite a bit but then started to discover swooping but still one of my most memorable canopies.

Besides you'd be jumping a collector's item.

A Stiletto has a relatively flat trim.
flat trim is great, but more I want fast dive recovery. not the same thing

Glide angle should not change with wingload.



in a perfect aerodynamic world, yes. but it does change. induced drag and lift increase exponentially with speed, but so does parasite drag.

***The question in my mind remains, why do you want a flat glide, and what do you consider flat?


I consider flat to be the 10/1 glide I can get out of some of the gliders I fly. of course I'll consider something less for a freefall designed parachute. :P

what I want is something that flies like my bullet 12m paraglider but is designed to be opened a few thousand times after freefall. I have jumped my bullet and i LOVE it but it was built like a paraglider and does not handle the deployment loads well.

Whilst we at it (and I hope this doesn't sound like a daft question) ... What is the best way to measure the Recovery Arc for a given canopy.... I can 'feel' that they are different on my Saber1, Katana & Nano but dont know how best to quantify it...

yeah I have no idea. Probably one of those things with so many different factors it would be harder to 'quantify' than even the glide of a canopy, though that seems like it would be easy.

I have done full 180' snap dives from well less than 200' on my bullet12, that would KILL a person on any similar sized skydive canopy.

that is hands off dive recovery though, on the bullet GTs you can do a low 180 but you have the help it through the plane-out.

but we are talking about skydive canopies. I have really only flown a stilletto. I have a dozen or so on a velocity and vengeance sub 120' canopies, those things seemed like they eat up energy very fast.

For you? Yeah, maybe.

The trouble is you'll get people with no paragliding experience buying Bobcats and going in under them because they're so different to fly than parachutes...

The Bobcat, Swoop, even early Bullets & Nanos are much more like paragliders than parachutes in their handling and need to be treated as such.

We've already got people buying parachute that are more than then can handle because they have mad skills. Now throw in 100sq ft canopies that react as twitchily as the Swoop does to harness input. B|

True Will:( ... but that shouldn't stop them being produced (like small X_braced canopies)... We (?) Just need to be mindfull - we already have systems (?) in place - they just need to be adherered to.... I'm not sure what the answer is, but it [probably] isn't to stop development

Try getting hold of a PdF Springo 140. Flatter glide than a Stiletto, more responsive on toggles, great openings. It's great for everything except swooping, because it has a VERY short recovery arc. I think it might be what you're looking for.

About 8 years ago, Nervures ( manufacturer of the Swoop speedflying wing ) built and experimented a high aspect ratio skydive wing. I don't remember the details, but I think they had a 19m2 and a 17m2, with a plan form very similar to a paraglider. I believe this was a prototype for the military. Anyway, it's never been produced as a sport canopy.

Springo... that's what I was trying to remember.. It's used for Speed Riding too ... ah, the old grey cells spark back into life when kicked sufficiently hard... Thanks.



Just be careful with springos and turbulence. NOT a good combination.
