Beginner wingsuiter needs some advice.

Recommended Posts

Hello. I am new to this forum so I will start with a brief intro. I am Alexander. I have 498 skydives at the moment of writing this post out of which ~70 are wingsuit jumps. I jump at Skydive Stockholm in Sweden.

The best way to illustrate my problem is this video. This happened to me this weekend. The problem is it's the second time it has happened to me in 2 months in just 70 WS jumps. 428 other jumps, of which ~200 are in a high performance one-piece tracksuit (Airglide Mono) and never was even close to cutting away or having line twists like that. Needless to say, it makes me very anxious about jumping wingsuit, which is a shame, since that's what I was aiming for with skydiving. I want to try ws base one day, but with problems like that I know I shouldn't even think about it now.

Does anyone have any good suggestions, packing tips words of wisdom, how I should approach fixing this?

Current canopy is PD Storm 150, with a wing load of about 1.3.

 

Thank you.

One of my friend has around 150 WS jumps with a Storm 170 WL 1.1 and had 3 cutaways that looked exactly like yours.

Check this thread, all advice are in there and you can browse in the wingsuit specific forum for other inquiries.

I'm no expert on the topic, but like you, wingsuiting is my passion. I started right at 202 and now 540 jumps later I think I can shed some light and experience... I bought a brand new 170 storm for a worthy wingsuiting canopy.  GET RID of it!  I've put only 9 jumps on my new WINX 166 and  well, JUST BUY ONE! Can't rave enough about it...

Secondly, you need ALL the modifications, 9 ft bridle, dynamic corners... The biggest piece of advice I can personally give: PROPER FORM ON DEPLOYMENT AND FLY THRU IT.  Also, when you start flying a suit that can flare, the spicy openings tend to go away!

Couple quick things from watching the video. First, you are leaning to the right when you pull. You can see the horizon going wonky. That will turn your burble into a big ass vortex which will rotate your bag/packjob before it gets to line stretch like it happened in this jump. It also means that when you get snatched you get ragdolled to create even more twists. If the packjob gets thrown around it will also open harder as the slider will come off the stops before bottom skin inflation, compundng the ragdolling issue.

 

So dedicate a number of jumps to do practice pulls smoothly and slow concentrating in keeping level and being symetrical, as well as getting comfortable with flying the suit during the pull sequence. There's no rush to pitch in a wingsuit, we are falling relatively slow.  Also try and make sure you slow down first efficiently without dirtying the air behind you. The link above has some stuff about it

 

The other thing, once the twists are in full flow there's not much you can do to stop them, and all you might achieve by reaching wildly into the risers is getting your fingers trapped between the twists. What you can do though, is prevent the canopy from diving by ensuring the risers are level. So as soon as you see you are getting twisted grab the risers low down or at the three rings and yank the right/left risers as needed to make them even before the twists lock them in an uneven position. Keep the fight to maintain the risers level until the whole thing settles. With a canopy flying level you got more time to get rid of the twists and is way less stressful.

 

Besides that, storms are notoriously bad ws canopies. Just because they are 7 cells does not mean they are ws friendly. Other things you may want to consider are semi-stowless bags, 9ft bridal and big PC if you don't have them already.

If i had read through this^ first it would have saved me some writing :-)

Alright so a few things. It's a bit hard to tell everything from the video, so I'm making some generalizations.

- When you get linetwists the FIRST thing you do is get the risers even. Look at the slinks and make sure the left and right riser sets are even. If they are not, even them the fuck up pronto. Uneven risers are effectively equivalent to inducing a harness turn into the canopy by which the lines on top of the canopy are uneven. That effects a turn in the canopy and it will start to spiral down on you very quickly (which is what happened in your video). The more you spin under the canopy the more friction you're going to build in the lines making it harder and harder to even the risers up as you spin under the canopy. That's why it's important to get them even quickly, immediately open opening.

- The type of linetwists you experienced are called body twists. They are mostly specific to wingsuiting. They occur when the canopy opens without linetwists, but you spin under the canopy. It often occurs when the risers are loaded unevenly, which in effect throws your body in a spin as soon as the canopy starts to slow you down. The cause of this is failing to fly the opening correctly, and in almost all cases it's because you dipped one shoulder low which made one riser effectively shorter than the other.

To reduce the occurrence of dipping a shoulder low and causing this chain-reaction events, look at the horizon through the opening and keep your eyes on it so you have a reference. When you collapse your arm wings to reach back for the PC, fly with your shoulders to ensure you're still flying straight. Keep your hands on the BOC for a quick sec to make sure you dont start turning or dipping a shoulder low. You can practice this on a jump by flying your WS with both hands on your BOC. Try flying straight with only your shoulders.

-If you do have linetwits with uneven risers and the canopy starts to spiral down you, try to twist the linetwists down onto the risers which in some cases will allow you to straighten the risers up. If that doesent work in a very short amount of time, cut main away.

- You took too long to initiate EPs. Dont mess around with a canopy spiraling down. If you cant make progress on it within the first three seconds if it spinning like that, chop it immediately. In the USA, the first three fatalities of 2019 were all from what you experienced. Canopies that spiraled down on linetwits and the pilot ended up spiraling down too low. That has killed a lot of skydivers over the years. You burn through altitude very quickly when the canopy is spinning like that and you have less time than you think.

- The Storm is not an ideal wingsuiting canopy as it will spiral down easily like you experienced. However, far more important is flying the openings correctly and getting the risers even if you have linetwists.

Excellent post.

Much better than the, "you must buy this specific canopy / gear" type of post.
