Is this possible? How so? The two primary ways are: 1. Attach a second set of lines about 3 to 4 inches below the original tow points. You will also need to move the original tow point toward the nose of the kite, about 1 inch. Make new handles from about 3/4 inch diameter by 14 inch long wooden dowel. Drill a hole 1 inch in from each end and attach the fly lines accordingly. Normal flight is from the top set of lines and then when you want to put on the brakes, you simply rotate the handles to create tension in the bottom lines. 2. Make yourself a second set of long bridle lines. These will be attached, one on each side of the kite, between the leading edge bottom spreader connections and the center spine, bottom spreader connection. Now attach a second set of fly lines to these new bridle lines at a point directly below the original tow point. This method will provide a better possibility of casuing the kite to back up. You can experiment with moving the bottom line attachments toward the leading edge and toward the center spine to see what position best suits the control that you prefer. You should realize that no modification of a Delta will cause it to fly anywhere near what the Revolution does, However you can achieve some very interesting performance characteristics.

You need to make a new bridle for it. /|\ / | \ A-----B / | \ / | \ C-----D-----E / | \ You'll need four pieces of sleeving (or whatever you're going to use for the bridle). Connect A-D. Connect B-D. Connect C-D. Connect D-E. Attach clips as appropriate, and tune from there. As long as you make sure that AD and BD are the same length, with the clips in the same place, and make sure that CD and DE are the same length, with the clips in the same place, you should be able to do any other necessary tuning by changing the lengths of the lines you are using at the handles (put some extra sleeving on one pair of lines, and put in knots about every 1/2). If you don't like how the kite is acting, see what happens when you make the bottom lines a bit shorter or longer relative to the top lines. Flying your delta backwards like a rev doesn't work very well. However, you can land your kites a lot easier, stall it whenever you feel like, and get much better turning out of it. Good luck!

Is this possible? How so? | | Fairly simple. You need to make a new bridle for it. I've had pretty good luck quad-lining a Tracer clone just by adding two loops to the bridle. I attach two loops, one each about six inches below the main bridle pick-off point, with prussik (double larkshead) knots. I then move the main bridle up about 4-6 inches. Attach the top lines to the main bridle pick-off point, and the bottom lines to the loops, and you're set. It flies OK quadded, maybe similarly to an Ultra, but I'm not experienced enough with either to make a more meaningful comparision. It is still interesting to see a delta launch backwards off the nose. It isn't a Rev though. -- Lee Hetherington ilh@lcs.mit.edu = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Date: Mon, 27 Jun 1994 09:11:08 -1000 From: andrew@tug.com (Andrew Beattie) Message-Id: Organization: /usr/lib/news/organisation Subject: Re: making dual into a Quad In article <2tvk15$q61@fermat.mayo.edu> mhenderson@mayo.edu writes: >I've heard it is possible to convert a dual line Delta stunt kite into a >Quad line.

Have a look at Drachen Magazin 2/94 page 71... there's an interesting way to add "flaps" on the lower spreaders. Using quad/lower lines to control the flaps you have possibility to fly in dual or quad mode or something between. I have tried a kite called DV8 with similar flaps built in the sail. It was fun!
