LRM.
i am starting to understand what purpose it serves (i think). a line release mod makes it so that you can get rid of your toggle completely to clear a line over? ive seen pictures of jumpers with toggles in their hands, where the toggle lines were not appearing to be routed through anything. the lines went straight from the jumpers hands to the tail. is this the LRM?

if anyone could explain how this is setup a little more i would be very thankful.

In slider down/off packjobs, the brake line does not go thru the ring on the riser or the grommet on the slider. To clear a line over, let go of the toggle. Just as you say - the tail of the canopy is connected directly to the hands of the jumper. (The first time you jump a slider off packjob, this will feel sloppy and weird. You are not used to being able to move your hands all around without effecting steering.)

In slider up packjobs, you need the brake line to go thru the ring on the riser and the grommet on the slider, just like a skydiving rig. Why? If you had a brake release on opening and the line did not go thru the ring and could float up to the canopy, the slider could get fouled up on that line and hang up there... Also, the tension on the control lines in opening is part of the magic juju that makes the slider come down.

So, some manufactures have come up with unique ways to jettison the brake line from the toggles/risers to clear a line over on slider up packjobs, even when they go thru the guide ring and slider. Look at the photos and manuals and you will learn how the various systems work.

When you attend your FJC (that from PM's I know you are planning on) - you will learn a lot about these systems.

They're also good for coming loose when you're pulling out of a swoop and smashing you into the ground with a very loud "oh shit" just shy of the flag.

Or so I've heard.

Pack your shit right and carry a hook knife that you know how to use.

I venture to say there isn't a statistically significant number of S/U line overs that have been corrected with LRMs. Not significant enough to counter the more common incidence of inadvertant release. Anyone feel free to shoot that one down...just an observation.

I've seen 2 LRM releases...and a riser-over, which couldn't be helped with LRM.

Mutha bitch needed a reserve.

Not since the advent of the tailgate, anyway. Before that? Sure.



Can you give more details? Were these on opening? Or are we talking about a jumper accidentally dropping a toggle once they were in full flight? Or something else?

I've never seen a properly set modern toggle blow on opening. I've seen it happen with old style pin toggles, but never with a cloth stub.

The best argument I've heard for not using the LRM is that the incidence of line over with a tailgate is significantly lower than the incidence of a blown toggle on opening, and that if your landing area cannot take a riser landing you're better off risking the line over than the blown toggle. This would only apply in very tight landing areas that are more or less surrounded by obstacles like trees--making a sinking approach extremely touchy with risers, and any other approach impossible.

That, of course, means that the landing area here is just fine (since landing on risers here isn't too tough) for the LRM.

If you're talking about dropping a toggle once you're already flying (say, because you are holding it loosely to make a swooping approach), then my solution is just not to do that.

What about with an unvented canopy? I have heard recently that an unvented canopy doesn't fly to well if you lose a toggle with the LRM. I guess it would be the same if you broke a brake line or two with a slider up unvented canopy too.

I once cleared a line-over while using the LRM without letting go of the toggle. With the increased free-range of the control line, I was able to pump/whip the line thereby clearing the line-over.

The LRM drops I saw were on opening...seen a half dozen - all S/D

edit: What I was describing below was a WLO detachment.

Close...aggressive swoop...velcro came loose.

I'll elaborate when I see you, but you can probably fill in the blanks.

And Lanes...you just have mad Ninja skills. You're disqualified from the discussion bitch.

mutha bitch has a problem with the difference of LRM and WLO toggles.

This has not been my experience.

I can't tell a difference between vented and unvented versions of the same canopy in full flight. In theory, in full flight, the vents are fully closed and the two versions (vented and unvented) should perform the same. That's what happens in practice, in my experience, as well.

Can you explain why the presence or absence of bottom skin inlets would change a canopies flight characteristics in anything other than a steep sink (in which case the vents may open to admit air through the bottom skin, which could make the vented canopy more stable in the steep approach)?

Disclaimer: Note the "may" in that last sentence. My experience has been that vented canopies are more stable in steep approaches, but at least one canopy manufacturer has told me that he does not believe the vents open in any flight configuration (only in a full stall).

both types of canopies in described conditions flies the same. Flies so that the extra care is mandatory.
be careful w input on front and rear risers on turning.

Yes, it got convoluted. Fixed it.

edit: mutha bitch!

Nope, but from what the guy who had experienced it said, 1/4 of the canopy shutdown after losing/breaking 1 brakeline on opening causing him to sink out badly(not from riser or toggle input) and miss the landing, not a good thing at that particular site.

It sounds like you're talking about tail flutter when the back 1/4 of the canopy is uncontrolled due to brake line release. I can't see that happening any different on a vented v. unvented canopy. They'd both do the same thing.

Did he have a similar jump on a vented canopy to compare it to?

Most likely, neither the side who think that vents help when the back 1/4th of the canopy is untensioned, nor the opponents actually have made "scientific" jumps with video to support their conclusions. In situations like this, when extensive tests are not feasible (who wants to make N jumps like a robot with vents/no vents with blown toggles), it makes sense to just make a guess that "makes sense".

Since vents were specifically invented to help the canopy inflation when for various reasons it's not so good, it makes sense that in this situation when the internal pressure oscillates due to the tail oscillations, vents probably do help.

It's like thinking that if somebody would choke me to death, ability to breath through the butt would come handy.

Not to sure.
