Pocket Sled Kite Measurements
I would like to make the Pocket Sled kite that is on your page titled 'The Sled Kite - Some Background'. The one in the first picture, very colorful.
Could you please put the measurements on your website?
Short answer: No. ;-)
Slightly longer answer: But you can view the original plans (as far as I can tell) here...
The Pocket Sled.
Longest answer: (Please read this, since it contains helpful hints on having success with those original plans!)
Well, my first thought was 'Heck, the only way of getting this information is to get hold of an actual Pocket Sled kite, then pull it apart!'
The next thought was to take a close look at the picture on my web page and, combined with some Sled-making experience, come up with a similar design just for you. Aren't I a nice guy?
This is exactly what I did. After 20 minutes or so, I had the new MBK Pocket Sled sketched out on an A4 piece of paper! Mmmm, it should fly, but I had better make one from garbage-bag plastic first, just to be sure.
At this stage, a little voice told me to go online to see what I could find. Not expecting anything, since this was a mass-produced retail kite. However, in the first page of search results, there it was!
There is a purple template on the left, and my guess is the numbers represent centimeters. Note the scallops (cut-aways) in the leading (top) edge. This is not an attempt at 3D, so you need to actually put in 2 small curved cuts there, so your sail looks like the template when laid flat.
The pink template on the right represents the ram-air pockets. Obviously, you need 2 of these, with one flipped over. The 2 longest edges of these pockets are sewn to the main sail, along the corresponding lines on the sail template.
Finally, the tails can be attached near the bottom edge of the sail. I would put them in the bottom opening of the ram-air pockets. However, this is a good design, and tails are not necessary for this kite to fly properly.
A quick'n'dirty version of this kite could be made with plastic bags and tape. Or, you could get serious and use rip-stop nylon and a sewing machine!
Have fun making a Pocket Sled kite!

Well, it was the same reserve and a similar time of day. A bit closer to sun-down perhaps. Only the kite was different - the Dowel Barn Door kite this time, chosen to suit the 'gentle' strength wind gusts of between 15 and 20 kph.
The first flight went well, with the kite soaring straight up on around 45 meters (150 feet) of line. The late afternoon sun glinting off the panels as the kite moved about at steep line angles. In the gusts and lulls, the kite had a tendency to pull to the right at times.
As I was taking the kite down to do a bridle adjustment, the main problem became apparent. The horizontal spar had pushed through the tip-tape on the right corner of the sail, drastically reducing the sail area to the right of center. It was actually surprising how well the kite was still flying, given the gross problem with the sail!
On a second flight, with the tip repaired, there still appeared to be a slight pull to the right. So, after taking some video footage of the Barn Door's antics, it was brought down once again. This time the bridle knot was taken across by about a centimeter (1/2"). That was better! The 1.2 meter (4 feet) span pale orange kite shot right back up, showing much less tendency to pull across when under pressure.
After some more video was taken, with the kite soaring around almost directly overhead at times, it seemed safe enough to let out more line. It was surprising to feel the flying line touching my jeans while it was anchored under-foot! How much rising air can there be at this time of day? At the time I was concentrating on keeping the wandering kite in-frame as I took video.
Finally, after enjoying the kite doing its thing on over 60 meters (200 feet) of line, it came time to pull the Dowel Barn Door down. When within 30 feet or so of the ground it started to float and sink face-down. Then it was an easy matter to pull in the remaining few meters of line, keeping the kite flying until the bridle lines were in hand.
Weather stations were reporting around 10kph average wind speeds with gusts almost to 20kph.
