Using Large Dowel Kites
These KAP reports document what happened when some aerial photography was done in our state of South Australia. The Multi-Dowel Barn Door kite used to see most of the action, with the Sled getting pulled out in winds that were too light for the Barn Door. Similarly, the Fresh Wind version of the huge Barn Door took over when the winds were too strong for my other kites. More recently, a Fresh Wind Sled has also been created, which has a zero rig-time.
Barn Door kite with KAP test weight
There's the huge Barn Door in the photo. A test weight is suspended in a bamboo tetrahedron which later became the cradle for my camera. Note the Half-Picavet arrangement.
This design starts to struggle around the 28 kph mark, so another Barn
Door design has been created. This 'Fresh Wind Barn Door' uses the same diameter dowel, but has much less sail area and a whopping big hole in the center. It flies right up into the 30-40kph range.
Although suited to stronger winds, the Multi-Dowel Box kite has so far proved awkward for KAP. This design has a much longer setup time and is prone to sinking out to the grass when you are trying to get the camera into its cradle! However, it did successfully loft the camera rig on one occasion when the average wind strength was high enough.
Recently, a new skewer rig design has seen some action. Lo-tech
materials are something of a theme on this site, you might have noticed
by now :-)
advantages of this new rig include faster insertion / extraction of the
camera and full 360 degree view direction adjustment. Plus access to the
buttons on top of the camera while in the rig.
Fewer photos need be
taken at a time, since you can just pop the rig into the air and down again several
times if need be, shifting the point of view for each flight.
KAP Reports From Around Adelaide
And sometimes beyond. Adelaide is the capital city of South Australia, one of the windiest states of Australia. Still, you occasionally can't do KAP at all, due to 'no wind'! Perhaps a large R/C blimp would come in handy on those days.
OK, here are the reports. Most recent ones first...

Port Adelaide - 1 (Fresh Wind Sled)
Marion Shopping Centre - 2 (Fresh Wind Sled)
Flinders University - 1 (Fresh Wind Sled)
Happy Valley Reservoir - 2 (Barn Door)
Marion Shopping Centre - 1 (Barn Door)
Brighton Beach - 1 (Sled)
Meningie Fair - 1 (Sled)
Adelaide CBD - 1 (Fresh Wind Barn Door)
Noarlunga Centre - 1 (Fresh Wind Barn Door)

E-book special of the month (25% off)...
e-book takes you step-by-step through making a 119 cm (4 ft) wide
Parachute kite. It's not quite that wide in the air since the
canopy takes on a distinct curved shape when inflated. This 14-cell
kite performs best in moderate to fresh wind speeds. That's 20 to
38 kph or 13 to 24 mph. In gentle winds, this kite will hang in
the air at fairly low line angles. In fresh winds, it pulls
firmly for it's size, so small kids should only fly it while
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 Parachute 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.

Winter-like weather has been the norm here for many weeks. But today was sunny with very light winds. A rare opportunity to take out the tail-less Della Porta variant with it's latest mini-bridle conf…
