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.
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 :-)
The 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.
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...
