2-Skewer Dopero Takes To The Sky
(Rockingham, WA, Australia)
Dopero kite ducking the showers
There's always a certain feeling of trepidation when you've spent a week or more on a project, and then crunch time comes. Especially when 'crunch' is the last thing you wish to hear.
As I crossed the road to the park (how lucky am I?), with the kite pressed against my chest by the wind, I started to worry that the wind was too strong, the glue too weak, the spars too flexible, etc etc...
Attaching the flying line, I let out about 10 feet of string and had a quick fly - not good, very wobbly. Feeling that turbulence was the cause, I pulled about 20m of line out onto the grass, and tried again. Once again a few wobbles, then at about 15 feet, in cleaner air, up it shot.
All the line was out in what felt like half a second and was probably closer to 20, with the kite pulling strongly and evenly, then with all the line out it climbed almost straight overhead. Stronger gusts would knock it back to about 45 degrees, but it always recovered to fly around 70 to 80 degrees.
After about 10 minutes in humid weather with a few raindrops, it developed a tendency to lean and fly to the left, and do loops during the gusts. Time to pull it down.
As expected, the humid windy conditions had caused the glue to soften, resulting in uneven dihedral in the main sail. Back home now, I've added an extra skewer piece at each front spar join, and resolved to only fly this kite in sunny, calm weather.... but it handled the wind so well!
Thanks, Tim, for another great kite.
E-book special of the month (25% off)...
e-book takes you step-by-step through making a 120cm (4 ft) tall
Parafoil kite. This 4-cell kite performs best in gentle to moderate
wind speeds. That's 12 to 28kph or 8 to 18mph. Even in light
winds, this kite will hang in the air, although at low line angles.
In fresh winds, it pulls firmly for it's size, so small kids
should only fly it while supervised!
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 Parafoil 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.

This previously published page is a mixture of informative data and historical background. Also there is also a video of one of my own tetrahedral designs in flight!
