(1-800-827-6364) Subject: Flexifoil stack I have a 6' flexi and am considering adding a second to my bag to stack. I have been told that as you stack these the wind needed decreases. Is this correct? Does the stack fly slower in the lower wind? I can understand that the more sail area you get in the sky with the weight of the lines spread over 2 kites would allow you to fly in lower wind, but I think the speed would be unimpresive.

Can anyone help? > > Thanks, Marc During my somewhat limited time as a kiteflyer ( approx 10 months ) I have progressed from a single 6' foil to 3 in a stack. It does appear to me that 2 will fly in less wind than 1 and similarly 3 in less than 2. It certainly seems true that the stack flies slower in the lesser wind. Please do not take these answers to be the final word, I am only passing on what experience I have.

It is the case that _any_ stack of N+1 kites:- 1) flies slower 2) generates more lift 3) launches easier than a stack of N kites. The same goes for a stack of 2 kites vs a single kite. This all assumes that the kites are all the same, correctly tuned and bridled and are stacked properly.

You have nevr tried to launch 50 or more flexis or any other type of dual line. Getting 80 trilbys in the air is almost as hard as holding on to 'em. ___________________________________________________ email: crowell@kite.com FTP: ftp.teleport.com/pub/users/crowell WWW: http://www.teleport.com/~crowell Kites By Carl Crowell - O.S.F.M.

I cannot say the same for a stack. Personally I would modify 3) to read: 3) harder to launch from all but the most straightforward attitudes. John Travell.

Also, the stack flies slower in the same wind. It is a different beast, slower powerfull, more of a giant in all respects. I have found a stack of 6 (with an ultraflex in the top kite) to be a reasonable zero wind kite, but I did break 70lb line doing it :-) Andy -- ____________________________Andrew Hawken______________________________ "However many ways there may be of being alive, it is certain that there are vastly more ways of being dead" R Dawkins.
