Sled Kite - Reducing size of Dowel design

by Leslie
(Fairbanks, AK, U.S.A.)

Q:

Can I make the 48 inch Dowel Sled kite with 36 inch dowels instead?

I would be reducing the overall design by 1/4.

Will this work? Will its flying ability be affected?

How?

A:

The down-size should work fine, since you will end up with something similar in dimensions to the MBK Simple Sled. However, the cut-outs of the Dowel design do add to its looks!

Just be careful to check and double-check that every measurement is multiplied by 0.75 to reduce the whole thing by a quarter. The size of the cut-outs don't have to be super-accurate, but the distance down to the towing point does need to be reasonably accurate. Taking the dowel width down to 1/8" would be a little thinner than a strict 25% reduction, but should still work fine.

Try to find plastic that is a bit thicker than the cheapest garbage bag or garden bags available. This helps prevent the leading edge from folding under and collapsing the kite. Even at 3/4 size, your Sled should easily make it to 300 feet or so after you get it out of the rougher air down low!

As for flying ability, those 1/8" spars should make it a little more lightly-loaded than the full size Dowel Sled, so its light-wind performance might be even better!

Just to get you enthused, here's a flight report of the Simple Sled, which is also 36" tall and made from 2-ply orange garden bag plastic. The slightly more expensive bags, compared to the ultra-thin cheapies.

Hope to hear of some good flights!

E-book special of the month (25% off)...

This printable e-book takes you step-by-step through making a 120cm (4 ft) diameter Parasail kite. This kite performs well in gentle to moderate wind speeds. That's from 12 to 28 kph or from 8 to 18 mph. It pulls hard for it's size, so should not be flown by very small kids!

Every kite design in the MBK Soft Series satisfies the following points...

  • Materials are plastic sheet, tape and line – and nothing more!
  • Tools are a ruler, scissors and a marker pen - and nothing more!
  • All cuts are along straight lines.

For the greatest chance of success, I make recommendations regarding the materials. For example, the type/weight of plastic, type/width of tape and line type/strength. Close enough should nearly always be good enough, since the design is well-tested and should be tolerant of small differences from my original.

Get the e-book for making the MBK Parasail kite. After making your first one in plastic and seeing how it performs, you can try soft Tyvek or rip-stop nylon for your next build.

The e-book is a PDF file - which means printable instructions to refer to while you make the kite. It also means convenient off-line access if that suits you better.

"30+ years ago, I tried making a kite using the 'instructions' in a free kite-safety booklet. What a disappointment for a young boy.

 Your instructions and methods are wonderful. You help the builder to focus on accuracy, without making it hard. Also, you use materials that are durable, yet cheap!"
