sounds too good to be true

[Steve Forslund]

Do you really think it has a 9.5 glide? If it does how did they measure it that precisely? The website says above 8 to 1 but they don't claim 9.5 to 1. The Area 2 with a much higher aspect ratio is only called greater then 9 to 1.

 

Sounds like the k2 is only using super duper Skytex 40 deperlant for the leading edge with the rest of the top and bottom being Skytex 27 classic. The Cima is using Skyte 9017 with the special treatment.

 

I am sure it is a nice glider but I think you are over selling it, though it does sound like the right fabric for around here right now.

 

Remember waterproof fabric does not guarantee making a rain proof glider. With Dacron hangs performing better then mylar and other high tech fabrics. When water beads up it can raise the stall speed and make wings divergent.

the stiching holes will allow water to drain fast enough.  the fabric is amazing.  It brings mountain weight to heavy weight durability and with zero porosity.  if a fabric claims zero porosity then how can it even get wet to begin with?  we did a test where a pint of water was poured into a depression in the glider and after 45 min the water had not wetted the fabric at all.  jsut shake it off like it was a plastic bag and youre flying again.  The dynamic response of a wing wich weighs half of a traditional glider, making it 3/4 the total mass in flight, is much more responsive than the old school as well.  Light wings will be making big gains in the next few seasons, and the water tight cloth makes even more sense!  Let me know if you want to try one.  The cima k2 is a 1/2 en B certified glider, but has 9.5 glide and packs super small and lite.  ah ya it also goes 43 kph!

Don't forget to put some drain holes in the back of that wing. That

Sky is now making wing which are waterproof!  Their new fabric is non-
absorbent and also super lightweight, so in a light drizzle or morning
dew you just give a shake and it comes right off.  Plus the super light
weight of the fabric makes no wind launches and kiting easy, even in the
rain!

They intentionally call it low on all their gliders because they dont
want to defend that claim later on. They figure if they make an
excellent glider, then people will find out that it out glides
everything and also maintains safety despite less A/R. Reputable
glider companies do not post glide ratios often, so if they do it is
usually conservative rather than unrealistic like you would expect.
Unfortunately there is no really definititive company to test and post
G/R numbers. Did you mean the antea or the ares2?
