The Adelaide and Noarlunga weather stations were indicating ideal winds for the big Multi-Dowel Barn Door kite. In kph, the 10 minute average was in the teens while gusting into the 20s.
On arrival at the large grassy school oval, there were thin patchy clouds about and plenty of sunshine. It was around 2:30pm so the sun was high and clouds were still forming, marking the tops of thermals.
However, by the time I got the camera in the air I knew the thermals would be beginning to fade.
A small clubhouse provided a handy verandah on which to rig the kite, away from the breeze. Next, the garden hose reel was installed over a large bolt at the base of a light tower. Sometimes there is scope for creativity in finding anchor points for your kite!
It seemed a good idea to first put the kite up on 60 meters (200 ft) of line, with nothing hanging. Just to see what the air was like up there. This was soon achieved, although the big blue kite did shudder from time to time in gusts and turbulence.
Whether it was thermal turbulence or just rough air from the suburbia upwind, it was hard to say. Anyway, as the huge BarnDoor lurched about, it recovered itself time after time after time. Instilling confidence that it would do its very best to keep the camera safe, later!
Not game to loft my Pentax Optio G-2 just yet, I walked out to the 30 meter point, running a gloved hand over the line to bring the kite down. My tetrahedral bamboo skewer KAP rig was in readiness, containing the test weight that is just a little heavier than the camera.
Up went the KAP rig, as I retraced my steps back to the anchor point. There it is in the photo over there.
Then it was just a matter of waiting and observing. There were some interesting moments as the rig swung wildly a few times. But overall, everything seemed under control. Good! Still, I gave the kite a good 20 minutes up there to really prove itself. Or rather, to prove the kite / rig combination.
By the time I decided to attach the camera, it was clear that the wind was becoming milder and hence safer for KAP. Mind you, the camera would be fully enclosed in a bamboo frame which should provide very good protection from quite a fast descent to the ground. The Optio WG-2 camera also happens to be designed for extreme sports and hence is 'everything-proof'. Well, quite a lot - including fine dust, water, shock and extreme cold!
So, the moment had arrived. I walked out to the 30 meter point and put a wrap of line around one foot to hold the kite. Meanwhile, I got busy with the fiddly business of removing the test weight, inserting the camera into its sleeve and doing up a shoelace tie to hold it level. The timer was already active, waiting 5 minutes before it would fire off the first shot.
A jogger detoured suddenly, not wanting to hurdle the line between me and the reel.
Yours truly has been making noises about KAP, via the newsletter mainly, for over a year now! Or is that closer to 2 years. Aren't you glad there's been some action at last...
By the time the first shot went off, the Multi-Dowel Barn Door kite was
heaving around on a 90 meter (300 feet) line. Aren, my 7 year old boy,
was directly underneath, peering up with his hands on his bike helmet.
See over there in the photo.
The camera stayed at this height, although nearly 30 meters (100 feet) lower than the kite. I was relishing the sight of the $300 Pentax doing what I bought it for, so many months ago. Most of the time, the line of sight to the KAP rig stayed around 40-45 degrees from horizontal, putting it roughly 100 feet off the grass.
As expected, wind conditions did calm off, and kite settled down nicely after a climb to over 300 feet. While on 135 meters (450 feet) of line, a thermal boosted the kite nearly overhead. This put the camera about 350 feet from the ground, which was enough to fit about half the oval into the field of view.
The large photo below, showing two cricket pitches side by side, was taken around this time. The lawn-mower swaths are narrower than in other photos, indicating the extra height. The pale strip in the top right corner of the image is a 4mm bamboo skewer, just a few centimeters from the lens.
The afore-mentioned jogger ended up in just one frame of the 60 shots taken during the kite's KAP flight. The shots were taken at 15 second intervals, the camera refocusing by itself each time.
Realizing that the timed 20 minutes should have elapsed by now, I brought the line back in to 30 meters once more.
After much fiddling, including making a short movie focused on the grass (!), up went the bamboo tetrahedron again. This time taking video, after I had caredully focussed the camera on some trees at the far edge of the oval. Hoping that the distance was about right. The focus is fixed for the duration of the movie.
Well, it worked, but I think I will be trying a half-picavet suspension next time! The drogue hanging off the back of the rig actually made things worse by jerking the rig into rotation from time to time. Enough to make you giddy, watching the resulting video! Thankfully, there were also periods where the rotation settled down.
This whole outing was not too disappointing for a first attempt. Really, it was very satisfying. Many small things have been noted for next time. For example, inserting the camera into a sleeve is far too fiddly. A Velcro flap would work better. Ditch the drogue and try a half-picavet suspension, which isn't much more than a loop of line attached at two points to the flying line.
Most importantly, it will pay to fly the kite over more interesting terrain! On this occasion the camera saw a lot of grass and not much else. I also think that in general, an angled camera position is going to get more interesting images. We'll see.
Most pictures were reasonably sharp due to good lighting and the resulting fast shutter speeds.
And did you think I would forget the customary wind speed readings? Of course not. Sitting on a post, the meter recorded an average speed of 7.2kph with gusts to 22kph. So, early in the flight, gusts might have been reaching the high 20s, up at several hundred feet. Nothing that the huge Multi-Dowel Barn Door kite can't handle!
