Stiletto off heading openings

Recommended Posts

Not to be an ass, but are you sure you have your legstraps even and you're semetrcal when you deploy? I'm guessing yes, since you have 500+ jumps, but I wanted to make sure.

Also, is the Stiletto new/how old is the lineset?

Dude, it's a stilleto. It's notorious for off-heading openings. Many high performance canopies are...

I'd say learn how to steer your opening with rear risers, because it probably isn't going to go away.

I am reasonably sure this is not a body position or leg strap problem because I have made a number of jumps just to watch the canopy open and watch what is going on. I think this is more of a packing issue. The canopy only has 200 or so jumps. My wing loading is ~ 1.4



if it consistently one direction, check the length of your break lines from the toggle stow point to the cascade...

film you deployment and watch in slow motion.

you will find it is the nature of the design.
the center cell catches air first and instantly pressurizes the canopy via the crossports. the canopy expands and with the slider up the leading edge canot expand straight and snakes until the slider is about 1/3 to 1/2 way down. it is this violent snaking of the leading edge that causes off heading deployments.

Jeff, if it opens "OFF" heading "Then the opening wasn't great"...



Yeah, it is. I don't mind the mildly off-heading nature of my Stileto openings. I consistently tell people that I think it opens great, considering what it is.

What is it? A high performance canopy. People who love the Stileto love it because it "turns on a dime". People that hate it hate it because it's "twitchy". Same thing. It's a high performance canopy.

It is very sensitive to brake line length, symetrical deployment, and symetrical body position through the entire deployment. It's so sensitive to these issues, that it's nearly impossible to completely control all the parameters required for a perfectly on-heading opening. This is the nature of the beast.

As long as it's with +-45degrees of my original heading, I consider the direction 'good enough' to keep me out of impending canopy colisions.

If it's consistently more then 45 degrees, then check your brake lines for twists, and be watch for any body movement during opening. ANY body movement will affect the canopy. A good trick I learned was not to watch the canopy or the links during opening, but watch the horizon. Watching the horizon will help keep your body straight in the harness.

The canopy will start to turn just as the slider is coming down. I can almost always stop the turn with just body input, I seldom have to grab a riser. Not complaining but does anyone have experience with this? What causes the left side to open first?



You should call PD for a line length chart and have those lines measured. Spectra lines can shrink from the slider grommet friction especially those outer most lines!

If you want to try and get more on heading openings, try to pack more evenly and symmetrically.

I would recommend against stuffing the nose "way back into the tail". This is unlikely to aid a good opening but makes it easier for brake and d-lines to get in front of the nose. A better procedure is to fold the outer 4 cells, as a group, in toward the centre cell once. This is unlikely to have a significant effect on opening speed but increases the chance of an on-heading opening.

The slider should be "cloverleafed", evenly, in the middle of the pack-job.

This is advice, as given to me by Scott Miller of PD.

Welcome to the world of the Stiletto. The way the canopy flies is worth it tho...
-jp-

PS you could try to carry a little bit of foward motion in your deployment......(used to work for me)

You're not as good as you think you are. Seriously.

you have written instructions? my guess it's the one with the guy flying the original sabre on the front of it... That's the one I got with my velocity, I kind of cracked up. To their credit, they did send a supplemental appendix for the Velocity specifically. They do need to update their manuals though. And quartering the slider is recommended.

Was in a supplement for the Stiletto. Said to pull the slider out over the nose.

BTW, I had hard openings on my Stiletto (bought new) for some 800 jumps. Eventually I sent in in to PD to have it looked at, and it came back with a bigger slider... opens fine now.

The only sure way to survive a canopy collision is not to have one.

For what it's worth, give this a try. I have the same type of opening you mentioned on my 135. While at the CSS turkey boogie I talked with woman jumping a stilleto and she said she rolls the nose 4 and 4. I watched her do it and then did it myself. the opening was noticebly better. So after flaking the nose roll 4 ,leave the 5th alone and then roll the last 4. My opening was about as on heading as I've had from my stilleto to date. Hope it works for you.

I've done that on occasion on my Stiletto and it did seem to make a bit of a difference, but mine opens on heading 99% of the time already.

When you roll 4+4 don't roll it tight. Just a couple of loose rolls and pull the center cell out a bit to make sure that it catches air first.
