Javelin RS Sizing Question

Recommended Posts

Yeah, It took me a while to find it in previous posting but. I was just wondering...sizing charts are hard to keep track of these days. The RSK series is tiny...I going to be putting an 84 in there...I was just debating on a 106 or 113, either one will fit...but I am putting a Cypres in there as well. Doing a little fact finding to make my riggers life a little easier.

a 95 onyx fits beautifully in my rs.

note: the x-brace onyx is 1/3 lower pack volume than a tricell x-brace.



Unless the Onyx has been released, and I'm SURE I would have read about it's release, then what size Onyx will fit into an RS doesn't help him. He isn't putting one in his RS if he can't buy one yet.

I have put an FX-79 in my old XRS, it was tight, the FX-70 was a better fit. I believe the volumes for the XRS and the RS are the same, just different dimensions.

no need to be snipity, i'm making them as fast as i can. demo fleet is in que for production in about 2 weeks.



Snippiness was actually merited, because under the guise of being helpful, you merely took an opportunity to do more marketing.

Not that theres anything wrong with that at all.. Gotta promote your product line, even if it is yet to hit the market, but yes, a response pointing out that it was only of minimal help was merited.

So Dan is there anything that you canopies can't do?

According to your Ad's (er I mean posts)
They are better than everything in every way..

I bet they pack themselves too right?

"1/3 lower pack volume than tricell cross braced canopies"

that is a simple provable statement of fact.



1/3 less pack volume at the same size measured by the same measuring scheme? How is that possible?

I'm pretty sure non-xbraced to xbraced is about a 1/3 difference in volume, how is it that yours, WITH bracing, save so much space? are you saying that your xbraces take up no space? is it a much thinner airfoil? thinner fabric? less reinforcement?

inquiring minds MUST know.

tri cell cross braced canopies use 2 vertical non loaded ribs between loaded ribs. the onyx crossbraced quad cell uses only 1.

look at the posted pictures under 36 cell and it will make sense.

That would mean removing 9 of 28 ribs, leaving the top and bottom skin intact of a x-braced tri-cell would lower the pack volume by 1/3. The math doesn't add up, the 9 ribs are not 1/3 of the fabric, even accounting for the seams.

Icarus says that the VX packs about 25% larger than a conventional 9 cell. That means that the extra ribs and x-bracing account for the 25%. If removing the 9 ribs reduced the pack volume by 33%, then it would pack 8% smaller than a conventional 9 cell, even with the cross bracing still installed. A cross braced canopy packing smaller than a non-crossbraced canopy..............

the d cross braces are omited, the length of the crossbraces are shorter and and i beam seams are slightly less volume than rolled seams.

overall the 95 onyx was 1/3 lower pack volume as compared to a 99 vx.
