Title: Vortex Std or UL???
Post by: cojack_2107 on October 13, 2010, 10:05 AM
Hi guys, I'll be building my first Vortex by Christian Derefat soon. For the past few days i have been thinking, what should i do with the framing. Should i go with the UL to cover those low wind days or should i go for Std?? But i'm afraid that it might lost some tricks in UL frame.

I would appreciate it if anyone who have build and/or fly both the std and UL could give me some information on how the UL performs compared to the std.

Will it have limits to its trick capability or still obtain the same as the std. I hope that this question can be answered soon. Thank you in advance.

I have both, like both very much, but do prefer the UL.
Why?
I can do all the tricks with the UL I am able to do with the Std (even yofades and one pop yo-yos are stupidly easy), I get taz machines much easier out of it than out of the Std (might be me though), it flies in very low wind and it is more graceful.
It is just plain fun to fly it.

Thanks for the fast reply.  ;D what you used for the UL frame?? I got two opinion from two different person.

One said LE P90, Spine P100, LS PT3, US 5mm weight 12g

and the other person said ULE P90, LLE P100, weight 10g and the rest is the same as above.

Whats your opinion??

I've had my standard Vortex out in some pretty low wind (as low as 3mph I would guess) and enjoy the fact that it still holds up in the 18mph range.  I have been thinking about building one with a slightly lighter frame... but using tapered spars in the leading edge... so 5pts in the leading edge, with 5pt lower spreaders and 5mm upper spreader, with p100 spine.  My hope is that the slightly lighter frame will give it the edge in the low end of the wind range, but the flexibility might be forgiving above 10mph. 

I'm currently working on my Organic, so my new build of the Vortex is probably a month away... but if I remember, I'll keep you posted as to how it flies.

All that being said, if you have the means, just build up two frames and try them in the sail... I have no intention of changing any of the sail or bridle dimensions for my "slightly lighter than standard" version.

good luck with your build.

hope to hear from you soon. If its good, i might just use the same frame as u do. for now i guess i might just go with the UL framing as wind is often low in my area and maybe build a std one on the next session just to add to my collection. ;D

I built both STD and UL and I can confirm what nobble2k said, the UL makes the same trick as the STD so built the one which is more suitalble with your usual  winds. About the frame I asked directly Derefat before framing my UL and he answered me giving these solutions: 

P90 as LE, structil 6mm as spine, structil 5mm as US and 3PT as LS
3PT as LE and LS, spine 6mm, US 5mm

I made mine using the first one and I'm happy how my Vortex UL came out.

I'm just finishing my first build (le Quartz) and was wondering about the Vortex as my next project.

As a newcomer to building, can I ask what might be a daft question :-

Besides the framing, are there any other differences between the build of a STD and an UL ? I've looked at the plan and can't see any mention of STD / UL differences. Have I missed something ?

Also, are the bridles different in any way ?

I've done building my Vortex UL... i used the same bridle as the standard given on the plan and i used lesser weight. +-10g.. at times when the wind pick up i add another 5g but placed it closer to the center T with the 9g right at the tail. Flew great though. And ouw ya... customise the turbo so it can be adjusted to 3 point or longer turbo line. :) hope it helps.

My UL differs from the STD only in the mylar panels: in the STD I used 75gr mylar and in the UL 60gr mylar.

Hope to see you exercising this at Lyme sometime soon.
