V-Quad 20 MPH Blowing Sand Test

V-Quad 20 MPH Blowing Sand Test

Post by P. K. Ki » Sat, 15 Feb 2003 12:47:40


 As a follow up to the V-Quad development, I had a lucky day. I had put the
vented V-Quad in my Van, and while I was out and about, today, I decided to
take my chances with the wind and drive over to the beach.
 The sand was blowing on the beach at Grayland :-) Odd, too, as there was
hardly a trace 10 miles inland... it was coming straight from the south, a
bit bumpy, and not quite as steady as those perfect winds from off the
water.
 I didn't have a wind meter, but I think I started with about 22 MPH of wind
and an hour later, when I quit, it had dropped off to around 15, because the
sand quit moving :-)
 Success! The wind seems to pass through the venting with no problem. The
kite still wants to go like a bat outa hell when traveling forward and it
generates a fair amount of pull when it's roaring forward, but when stalling
it anywhere in the window, the pull is minimal, and slow motion movements
are possible... slow propeller moves, four-point turn-and-stalls, etc.
 I hate 20 MPH wind. I am a 5 MPH guy :-) But... this kite was pretty stress
free at 20, except when it screams forward (by choice). Still... I think I
would rate this kite a 5 to 20 MPH kite, with it's peak performance (IMO)
probably somewhere around 12 to 15 MPH.. To make a kite for over 20, I would
vent one more panel, I think :-) It will fly at 3 MPH, as I found out,
yesterday, but you are pretty much in a 3D mode at that point, and saying it
is a 3 MPH kite, is pushing it a bit, IMO.

 It was one of those days like you get at a kite festival when the wind is
blowing hard enough to make everyone get off the beach and go eat Pizza...
so, I feel like this test of the vented version was a great success!

Hey sweet! How does the control feel? Could you get it to slide backwards in
those winds?
What sort of pull was it giving you; I.E. what weight lines are we talking
about?
It sounds like a non-vented version could be a lot of fun around here, where
we mainly get 5-10mph.

Have fun picking the sand out of your hair...

 It feels much like a Rev and yes, it flies backwards very, very well, but
it also responds well to dual-line delta control movements.
 If I were to design (if you can call it that) a set of handles for this
kite, as well as many of the other similar quad-line kites that I have made,
they would simply be a 12 inch piece of rod bent into a mild horseshoe
shape... very mild bend, sort of like when the moon is new and only a sliver
of it is showing in the sky. I would pad the center portion.
 If all the flylines are equal length, you would hold the handles near the
center, but choked "up" just a bit... but no where near the top of the
handles, like you do with Revs. This stops the V-Quad from lunging forward
without you wanting it to.
 IOW, when you hold Rev handles near the top and you are flying a Rev type
kite, the kite is in a forward flight mode. You pull on the bottoms of one
handle to get it to turn and both handles to stall it. With the V-Quad and
horseshoe/moon-shaped handles, you hold the handles more near the center and
the kite is in a stall position. Tilt the top of the handles toward you to
make the go forward.
 This is not rocket science at all... just something I've noticed through
the years. Rev handles will also work with all of my kites, and that's
actually what I usually end up grabbing to fly them... but that Rev handle
shape, with the bend near the top, is not necessary for my kites, IMO. Also,
I hold the Rev handles more toward the center with my kites than I do with
Revs.

 I think I was using 80 or 90 lb. spectra. That should be fine with this
vented V-Quad. I doubt you would ever need anything stronger. Even in 20 MPH
wind, the pull is never enough to make you have to lean back. The pull is
pretty wimpy... it wouldn't be enough to get a buggy moving, for example,
IMO. This vented version is a finesse kite... no doubt about it... not for
power.
 I hope to make a non-vented version next. My guess is I will rate it
(something like) a 0 - 15 MPH kite, or maybe even 0 - 12.
 Yes, here too, in the Pacific NW, we would hardly ever be able to fly kites
if we didn't have ultra-lights... even at the beach... but we can commmoly
get a silky smooth 5 - 8 MPH breeze... and that is my favorite type of
*wind*. I hope that a non-vented 7.5 foot V-Quad will be *magical* in that
wind :-)
 Big wind is rare around here and usually associated with storms, and not
suitable for fun flying.
