Been following the development in all the available speed gliders - so wondering what the improvements are in the 07 Nano compared to the 06 ?
Different colours and a redesigned harness and risers ?
What other improvements/alterations have been made to the wing ?
Last time I checked the Gin website still has all the 06 info
Skiing Vs Foot Launch
Submitted by Freeflyn on March 6, 2007 - 8:33pm.
This is from the guideline section of this site:
"Nano, the GIN Speed Flying glider must be used with skis. Using this product without skis to take off and land is forbidden and dangerous"
Why is it considered dangerous to launch without skis? I am new to this sport (approximately 200 launches) however they have all been done without skis. Can someone please shed some light on this for me. Has this recommendation changed for the Nano 07?

I will try, but I am guessing if its not the answer you want to hear it will be wrong - just going by your last reply to my post earlier.... Eye-wink
anyway my thoughts if you are interested... Smiling
Speed Flying - involves skiing down a mountain jumping over rocks and off ledges etc. which requires skis.
Speed Gliding - Launch at the top of a mountain - land at the bottom with no touches.
The reason for skis - to allow you to continue in a forward motion when descending a slope after landing a jump.
Foot launching in deep snow - how...???
You need to be moving/running forwards to get the wing to create lift unless you are flying in 25knots or more wind. This depends on size of wing because a smaller wing needs more wind/speed to get the lift. Its impossible to run fast enough in soft deep snow. Even more tricky halfway up a mountain when you are stuck on a flat plato.
Another reason - Speed flying can't be done on/over prepared piste in many areas, so you need skis to go reach the Off-piste fly/launch zones.
Has this recommendation changed for the Nano 07?
No... as posted on Gin Website - Nano 2007 information
"The practice of speedflying needs a good level of skiing. "
... and its the same for EVERY Speed Glider - when used in the mountains during the winter.
But nothing wrong with foot launching if your location makes this possible - you need to know your location well - if you need to land you will then need space and angled slope to foot launch again else you will have to climb back up or down to find another suitable relaunch.
IMO - Foot launching is best for low level hills and slopes. Not off-piste or mountain flying. You would need to fly it more like a paraglider to keep airborne - Very difficult as the speed flying wings aren't paragliders and don't create much lift - most are based on Sports Parachute designs (as is the Nano) also the wing surface area is to small.
Hope the above is of some help...
Can anyone else add more ?

I am not fishing for a specific answer, just why the recommendations the way they are.
I agree with your logic for snow covered mountains during the winter, it is impossible to run in deep snow. However, this does not address why it is dangerous.
I have foot launched several wings (even a couple of sport parachutes) in no wind to +20mph on relatively flat terrain. Therefore I don't see the issue of lift as being a potential hazard.
Thanks for the speedy reply!

No worries, happy to help when I can...

more info on why...

Why is it considered dangerous to launch without skis?
Lift isn't really the issue - its how you achieve it. If you cant get your forward momentum you wont get the lift and glide. As posted earlier its mainly because if you are halfway up a mountain in deep snow you cant run and relaunch - you could be stuck on the mountain and need rescuing.
another thought would be with the landings...
Foot launching - if you loose glide you have no option but to land at running or walking speed like a skydiving/swoop landing. If its rocky or uneven groung there is very high risk you could break an ankle or leg if your approach speed is to fast and you miss your footing or slip etc. With to much brake from a high speed approach you continue your forward momentum - meaning there is a risk that you could land on your back as you swing back under your wing. With skis you can keep moving forwards to recover the lift you need to continue.
So I would guess its more for personal safety ?
running and planning

"As posted earlier its mainly because if you are halfway up a mountain in deep snow you cant run and relaunch - you could be stuck on the mountain and need rescuing."
I am talking about launching and landing with no snow. This is possible and safe, I have done a couple of hundred times.
"if you loose glide you have no option but to land at running or walking speed like a skydiving/swoop landing."
I do agree that this is an issue if you decide to fly a route that is not known (to you), however, this is completely preventable with appropriate training and planing. Site and flight path selection is critical is this game.
Nano 07'
Submitted by Stoylen on March 2, 2007 - 1:59pm.
The main improvement as I see it, is the diagonal ribs. This makes the glider more stable in flight. It does not pulsate as much as the 06'version, which makes it feel safer and more easy to handle.
Best regards

cheers for the info...
also just found this

which has info too, but its in German. Has close up photos of the Leading Edge.
diagonal ribs
Submitted by Freeflyn on March 2, 2007 - 10:27pm.
Is the cell height of the 07 nano smaller than the 06 as a result of the introduction of the diagonal ribs (more rigid wing)?
Cell hight of the Nano 07
Submitted by Stoylen on March 4, 2007 - 5:11pm.
To help you with your question I have measured the midle cell of my Nano 07. It measures 15 cm in hight, and 44 cm in length. I do not know the facts of the Nano 06, so I can not compare the numbers, but perhaps someone else can?

Ah...of course. That is essential:) The 14 sqm. Hope this will help.

Not sure from the photos
Submitted by kitesurfa on March 3, 2007 - 1:46pm.
Not sure from the photos, but the new Leading edge and X-bracing makes it look like a more narrower wing profile.
