Front risers on the Diablo.

[jumper03 0]

I'm jumping a Diablo 190 that right now I am loading at 1.05. I have about 150 jumps on it and decided to start playing around with riser approaches.

However, my first pulls on the risers up high were suprising. First, I have to do a pull up on the riser to get a response - very heavy pressure - and when it does start to turn, it 'bucks'. Coming off the riser is kind of ugly too - nothing smooth about it. I'm not so sure I want to be doing that near the ground

Is that characteristic of the Diablo or because of the loading? Any other Diablo jumpers notice this?

There've been some posts in the past about this. I haven't noticed, but then I use my toggles for turning. I'm a big wimp who doesn't really want to swoop or get scared close to the ground

There is nothing more dangerous than breaking a basic safety rule and getting away with it. It removes fear of the consequences and builds false confidence. (tbrown)

If your canopy start to 'bucks', check your steering-lines.
It seems to be, according to your explanation, that they are too short.

When you are in full flight, pull down both risers and check if the tail of your canopy is beeing pulled down by the steering-lines. If it is, then they are to short.

Start from flying in brakes, this makes the riser pressure less heavy.

You can find enough information if you use the Search function on this forum.

Hope this helps

My diablo is awfully LIGHT on the frontrisers, much lighter than both the spectre and the vengeance I flew before. I can EASILY hold 360 and I'm a wimp, didn't get past 270 on the vengeance... My WL is 1.3 or so. Checking your brakelines might indeed be in order! Bucking is a sure sign of braking

The advice about the steering lines is good. Steering lines often shrink the most because of having the most friction/heat applied by the slider. I have seen several canopies that the tail deflects just by reaching with the toggles to grab the front dive loops.

wouldn't a senior rigger know that ?

I have a very similar problem with my Spectre. I'll pay attention to see if the back is getting pulled when I do a front riser turn. I have no intentions of doing this low, but I love doing it up high. The more spins I can do the better. Usually toggles are enough fo me though since I'm still pretty amateur under my 135.

Thanks

I was going to start my own post, but I wasn't sure what it was realy called.

I guess I should add, that the brake lines are fine.
Slight slack in full flight - that was the first thing I checked.

I was hoping to see if the was characteristic of the diablo.

What about line trim? Could they be reasonably out of trim?

Hey Steve, I know you'd have checked the above but what about when you are in 'front riser' flight? If you pull them down is all the slack getting eaten up or is there still slack?

AH!!! I see what you're saying. That I will have to check. I'm not a swoopy swooper so I didn't think about that.

*DOH* I'll see if that is it.

If it is though - I like where my brakes are at...damn. I'll have to adjust a lot of flying before I get back on risers then.

This shit is complicated.....

I had this problem on my Samura once.

I believe the problem was my chest strap was too tight, bowing the canopy. (I had forgotten to loosen it on that jump)


Try loosening your chest strap after opening, so it's nice and loose, and your canopy can expand.
That may not be it, but its an easy thing to check.


have fun

When I double front dive my Sabre 2 150 on landing, I do get "bumpy" dives some times. Brake lines are plenty long and lineset is new. I think the lower angle of attack makes it more susceptible to turbulence that you wouldn't otherwise feel going straight in? Front riser turns are fine though.

[icevideot 0]

How far do you pull the fronts down? I have seen enthusiastic (and strong) guys pull their dive loops almost to their chest. That distorts the wing's profile to the point that all kind of weird stuff can happen. Too much of a good thing is still too much.
Just a thought.

ALL the slack is gone on the front riser turn....the brake lines are tiiiiight.

So now I need to entertain the question - do I stay with my Diablo 190 which is getting kind of ragged out - lengthen the brake lines and relearn to fly it...

-or-

Start looking for a Sabre 2 170 which is what I was planning on doing soon anyway.

decisions decisions.

I need to win the lottery.

your not going to have to relearn to fly it when you loosen your brake settings. especially if there was slack before when you were not pulling the risers.

after you loosen the brakes, everything will just seem smoother.
