HMA and RDS on non crossbraced canopies.

[dsbbreck 0]

In another forum a question arose about HMA and RDS on non crossbraced canopies.

I'm interested in the opinion of the community.

there are a handful of canopies on the market that aren't crossbraced, but are very high performance canopies, soooo.. why not?

why not squeeze everything out of it... some people like the openings and performance of a crossfire/ crossfire2 for shooting vid. i wouldn't use and rds for that though..

the RDS is pointless, unless your in competition. and you get more "WAY MORE" of a performance boost with the thinner lines.

Quite a few canopies that are not crossbraced come with HMA lines now as the standard lineset, some are uber-high performance and some are relatively mellow. It seems as time marches on that a few manufacturers have seen an advantage in this type of line for one reason or another. Better trim characteristics, less drag, etc...

The Fusion, Nitro, Nitron, Blade, and Mamba all spring to mind as having HMA as standard so I don't think you could really "outlaw" the line type.

RDS systems are another story I guess... but I've never used one so I can't contribute anything meaningful there. Of course, I'm not a competitor yet but I might give it a try one of these days since I have a new rig on the way.

So when you comin' back to MH Dave?

I agree with Mark here on the RDS system in reference to it only being used in competition and competition training. It makes no sense to have an RDS system on normal fun jumps. The last thing I'd want to do on a fun jump where you pulled lower than intended was having to deal with the RDS system. Shit I didn't like it a couple of weeks ago when the DZ would only give me 3k for a hop n' pop. There was hardly any time to stow everything (I wasn't even using an RDS system) and get to the setup.

Now as far as knowing which is better HMA or RDS, I don't know? I know John Judy told me something slightly different last September than what Mark is saying.

really? are you sure you weren't mistaken in what he said?

the performance gain from going from vectran to hma. "the small one's" is huge. probably 2-3x as much as the rds.

at least this is what I have found and from what I hear others say, they agree.

I don't want to put words in John's mouth, but it was something along the line of "some people will find the HMA gives them better performance and some will say they think it's the RDS". But not having flown an RDS system, I can't speak much about the pros and cons since ... I know Jack. I am still planning on calling Joe B soon about him making me one though. But I need to pay off my JVX first.

does someone has experience with a canopy with vectran and HMA lineset? Is there any difference in the openings?

I got an old Nitro from a friend and a rigger put vectran lines on it. I haven't jumped it, but I guess the performance will suffer quiet a lot.

Any infos on that?

I find if you are just pulling the slider off 3k is no problem - even in winter in Ontario. For the full RDS, at the stage I am at I would want 4.5k and nice (summer) conditions.

yes it will. especially since the lines are continuous.

more lines, more drag.

You may be interested to know that PD is offering HMA linesets for the Katana now. I couldn't believe it myself at first, but it's true.

Yep, my wife just got hers back from the reline today. I cant wait to see how she likes it.

Good point. I pull my slider off on every single skydive I make with my Velo-equipped rig. It's faster than rolling and stowing and it gives you a much-less-restricted view of your surroundings.

Me? I would be all for HMA and a removable slider (plus RDS lines for competition) on an HP nine-cell. Actually, maybe I will reline my Sabre2 97 with HMA just for shits and grins next time.

I bet that'll be a serious monster. Sabre2, best under the radar swoop canopy

I bet some one could be fairly competitive in the zone accuracy event with that canopy. It's 1/3 of the comp!

My previous post above was obviously flawed in that I neglected to isolated on the PC and dbag when referring to dealing with the RDS for regular skydives. Yes I see the benefits of pulling off the slider on any skydive and in fact need to speak to people (like someone such as Joe B) interms of making myself a complete RDS for competition and training as well as the ability of taking just the slider off on all my other jumps.

is it the 750 hma stuff. or the smaller ones.

I wouldnt want that 750 hma on my canopy. If it opens hard the lines wont streatch or break. you just break your back instead.

500 HMA is what PD are lining the KA's with.

Personally I'm really happy. I think the move away from a line type that changes so dramatically over it's lifespan was a good one.

Yup, beat me to it.

My Fusion is far from the world's most high-performance canopy, but it has HMA lines. Loading it at around a 1.2, I'm not pushing it very hard, but even though the lower drag doesn't do much for me personally, anyone can appreciate the longer lineset life. The only thing I don't like is the cooked spaghetti look of the lines

well, congrats to P.D. for making the leap....

or the fact they lined it with spectra was a bad one.

but I agree, good move. you cant have that stuff on a HP canopy.

Steve, I don't know of anyone running a full RDS that can't "switch modes" in under five minutes. I keep my vectran RDS lines folded up inside the inner mudflap on my rig and my deployment system is connected with a Slink.

come see me in dublin, I will show you a way to do it without the slink, and it is easier.

Yeah, Hurricanes come with HMA standard as well.
