QuoteVery high aspect ratio.
I thought that might be the case, but I was told by Precision that the aspect ratio of the 27 was about the same as the 21. Huh... So what are the differences in flight characteristics? What size/loading was your 21?
Jason
icarus fx vs vx, xaos 21 vs 27 same aspect ratio.
only difference is 7 cell vs 9 cell with respect to line set. the 9 cell version will have a slightly lower spanwise distortion as with the same aspect ratio there is a shorter span between ribs on the 9 cell version.

Okay, we got lower spanwise distortion. Probably also a slightly cleaner wing chordwise (since the cross braces cover the entire chord, like Velocity & VX, unlike FX & 21). Same aspect ratio. Same shape? Airfoil & planform? Same trim? I don't know. Anyway...a cleaner, more efficient wing. The one improvement I'm looking for in the 27 over the 21 is more speed maintenance. Even if I've completely nailed a landing on the 21, even when I'm swooping along in rear risers, I feel like it decelerates fairly quickly. I've had slightly better luck on a Velocity. I wonder, will this quality improve on the 27? If it does, and all else is equal, I've found my canopy.
Jason
Oh yeah, the reasons I still prefer a 21 over a Velocity are: better openings and longer control range (I seem to prefer that, especially in front risers). It's mostly the openings though... the Velocity I jumped was like a box of chocolates.

And, presumably, the 9 cell will have slightly more drag due to the extra lines.

QuoteAnd, presumably, the 9 cell will have slightly more drag due to the extra lines.
I believe this is negligible when compared with the drag created by the wing itself (form drag). Especially if the canopy is lined with HMA, Vectran, or Spectra.
Okay, so after only 11 jumps on this canopy, I'm getting longer, faster landings than with my 21. It also carves very easily.
Oh, and this deserves a paragraph for itself... the openings are sweet! Just as nice as the -21 openings. All soft & on heading so far. High altitude, terminal, sub-terminal. Very nice.
Here are some other observations (comparing a -27 94 to a -21 98): the toggle control range is very deep, especially since I have them set about 1.5" longer than the factory settings. The rear riser pressure is higher and rear riser turns are slightly faster. Front riser pressure starts about equal, then builds much higher. Front riser turns may also be slightly faster.... It responds just a bit more to harness input. Forward speed in natural glide is a bit faster and forward speed after a speed building maneuver is a lot faster. It doesn't seem to dive too much more, but it feels like it builds up and maintains a lot more speed.
I might get a new set of lower brake lines, 'cause the ones that it came with are the two piece type that tend to snag on the guide ring. I like the single piece style with a small, double fingertrapped section, that sticks out for the brake settings.
I will say this: this is the canopy that I'll be using in competition.
Jason
Also, thanks to all at Precision (especially Chris) for getting the canopy to me so quickly. I couldn't believe it when my dealer already had it at the beginning of the weekend.

i have a pdf ninja 94, and my weight is 195 pounds naked.(2.57 w.l.).
I think this cannopy is really a good flight tool,because it fly horizontal when you wish,and deep dive whit front risers.
Accept oppinions.
blue skyes and fast,long and save swoops.

I heard to speak of some Ninja collapses in turbulence, in DZ of Ampuria and in another DZ.
I jumped Ninja 94, without turbulence, and I didn't see any collapse problem. But there was not turbulence in my jumps.
See Safety Bulletin No. 02/2002, Mandatory in http://makeashorterlink.com/?U39711051
I don't like the flying and openings of the Ninja, is very flat and very hard in front risers. Also the openings is not very progressive (my opinion), hard in begin and later with a lot of snivel.
The project and the ninja quality I thought very good.
