One of the most popular sections of the GWTW Forum has long been the Swap Meet.  A great place to sell old, seldom flown kites or to get great deals on used (gently flown) kites.  Only registered users can see the Swap Meet section, let alone wheel and deal.  1000's (literally) of kites have changed hands thanks to the Swap Meet.

Whoa, a quad that can also do stuff like dualie tricks.  That's got my attention now.

Thanks for keeping this updated Bill, I'm not building a Valor at the moment but I'm sure these notes and follow ups will be very handy when I do. It is much appreciated!

****One more note I thought I'd advise to those building a Valor. You may want to shorten the 3mm stand-off rods 1 to 1.5 cm to lesson the stress on the lower spreader rods depending on what LS rods you use 3pts, 5pts, or Nitros.

Thanks for any advise you can lend on the venting. Right now it's not flying to bad but there's certainly room for improvement!

Also ....I found that shortening the 3mm stand-off rods 1 to 1.5 cm from my original 24mm lengths might be advisable to lessen the stress on the lower spreaders for all Valors.

No Problem.  Im figuring out my color schemes so I can order mats for my set.  I had already planned on figuring out a vented  version  for use at Morro Bay when the winds hit 15+and came up with a rough idea.  I haven't gotten to putting it on the plans you sent me yet since I still have to print them up.  Ill mock up my idea for you when I get a chance.

Let me know how it works out and what winds your testing in.  From looking at it Im thinking you have too many vents and a lot of your balance issue is from where the vents sit in the tunnel.  If you draw lines from the nose to the standoffs, the triangle formed by it you usually want to leave solid and put the vents on either side so the wind is bled off before it gets to the tunnel.  I found from my own vent projects that you really want to leave the center of pressure in the tunnel intact since thats where a lot of the balance in flight comes from and relieve pressure from the wings and lower part of the keel depending on your target wind range.  I usually start with a vent at the center of the wing(aero center) and vent the lower half of the wing tip and thats usually good up to 25 and then I add vents to the lower part of the keel.  I never found reason to vent the keel from the midline to the nose.

One of the best vented duals I have ever flown is a vented Illusion.  Its one of the few vented that is almost identical to the standard in performance IMO.

Got a chance to test out the new valor 'Z' today in much better winds than my initial test flight fact they were pretty much lab grade winds off the ocean & I couldn't be any happier with it's performance so far, so far. The 'Z' is surpassing my expectations.

The Z has a slightly longer wingspan & taller ...with the LE straighter ...than the original Valor. It flies similar to the regular Valor ...with some input differences but is much slower. Tricks are all still there with perhaps some additional unique flying traits & some great precision. Sits deep in a turtle & rolls up easily. I haven't put any yo-yo stoppers on it yet as I still need to determine what position on the LE to best place them ....Sky Claws will be the eventual choice. I did a couple lifter launches with it which combed with a Lazy Susan followed by a JL  ...& a half lazy into a nice controlled fade. Both look sweet & are impressive! JLs are nice & slow ...needing a snappier stronger input to transition from the lazy - back into the fade position. It also does some incredibly graceful flat spins ...even going around an additional time when hit right.! I'm really loving this kite! I couldn't be any happier.  Grin

I plan to build more Zs ...& plan on tweaking the design to visually improve the upper perspective of the 'Z' but other than that I don't expect to anything else at all in the build.

Today was perhaps the best flying & best wind day I've had in a long time! Nothing beats a steady lab-grade beach wind ...especially when critiquing a kite ...particularly fine tuning a new design!

I just wanted to add one more bridle tweak that I tried today for those who'll be making their own Valor. It's been in the back of my mind for some time now & only takes a small alteration of the sail once it's finished.

Lately I've been seeing several kite makers move the bridle attachment slightly lower (beneath the center 'T') with good flight results and decided to try it out for myself today. Early verdict after flying today is that it's a positive change. It certainly didn't hurt anything. More time will tell & the small hole needed to make this change will not be a problem if you decide that you prefer keeping the connection in the center cutout area beneath the center 'T'.

I made the small hole with a cheap pencil-style soldering iron ...just a little larger around than the standard soldering iron tip diameter. You'll need to keep it small but large enough that your bridle knot doesn't bind. (I use a slip-knot style attachment due to is small size) I also put vinyl stoppers on the spine rod to keep it from moving & tearing the sail.

DON'T DO THIS! My earlier observations were wrong! After flying in some lab-grade off the ocean beach winds today I learned that my original bridle placement of the IH bridle line was the superior placement point for the Valor. Moving the bridle point down an inch below the center 'T' was a mistake. I should have know better than to jump to the wrong initial conclusion since my early test was in less than ideal wind conditions. I hope no-one has reached that point in their build & put a needless additional hole in their Valor sail.

Wow, that is one incredibly sharp looking kite!

Thank you for the compliment. I got a chance to fly in some lab-grade beach winds today & have noticed some definite improvements with the new added vents. I need some more flight time in stronger winds to experiment with the removable vent covers but the added venting has balanced the sail pressure greatly & it is flying quite a bit better than that which my initial venting attempts produced! Don't know if it'll ever reach the point of flying 'exactly' like it's unvented big brother but it's much closer now than it ever was.
