Having dabbled in the vented territory, we now head into the low wind regime. Instead of pulling out a light wind kite.....

Has anyone tried making a trapezoid shaped sail with a sleeve on each end? The sleeves would slip over the vertical spars on the back side of a Revolution.

Steering independence would probably be compromised, but it doesn't look that different than the Blast or Super Sonic series. Before I waste a perfectly good 3 mil garbage bag costing 75, thought I'd check in with the quad-jocks here.

Comments, thoughts, guffaws?

it reminds me a little of the Cosmic Kites Prowler Quad, but the Prowler had a tensioned rear sail.
I think that in reverse, an unsupported auxiliary sail might tend to collapse
but I'm no engineer :-|

I learned last week that technique is much more important than sail modification when it comes to light wind Rev flying.

But you go John, you know what they say about "Necessity."

Just don't forget to reinforce the trailing edge, particularly in the center. Supposedly, that kevlar patch at the center of the V is there for a reason.............?  Roll Eyes

John's mod would greatly reduce the tendency for one wing to flip around, that's the reason for that kevlar, of course if you're a good flyer you may have never experienced that  Cheesy

I see problems with drag during forward flight, even reverse flight, but then that's not really what you do with a rev is it? Unless like me about the most impressive thing you can do with a rev is a heart stopping dive to a stop/reverse and I've been known to "bounce" a few of those Wink but give me a break, I've only been flying them since 1990.

I personally would not put the time into such a modification simply because, with the right technique, a rev can fly fine in very low wind. However, this technique is great for individual flying, but when it comes to team flying, it can be applied, but is much more difficult and complicated. I tend to fly by myself more. It would be interesting to try outfitting a team with this mod in 1mph wind and see how it goes.

This comes to mind because at the team clinic last weekend, we had some trouble with light wind team flying.

Echo that. Man, I HATE trying to fly team in light winds.

Me myself I really enjoy light wind, but I've always been a bit deranged...... Cool John I have
tried that design and have never been able to make it work, it goes up but won't reverse
no matter what I do Cry...... Ben-- oh yeah I do the bounce thing at time on the dive stops too
some times.... Cool

Tried it with a 'skirt' about half that size and I found it did help in light winds in that you could  hit the drive button a bit harder in forwards. Reversing was harder, but not problematically so. At the end of the day I found the improvement was pretty marginal.
