MBK Multi-Dowel Sled
As before, rigging the big Sled today
was super-quick and easy. It takes more time to unroll the bridle from
around the bundle than it takes to join the spars and attach the flying
Today the line was stored on a
garden hose reel, to avoid getting twists in the line. A couple of small
tent pegs were easily driven into the rain-softened earth, to allow
line to be dragged off as required.
There was just a bit of breeze coming through.
the bridle lines with my gloved hands near the towing points was enough
to get some air lifting the leading edge. In no time, the whole sail
had filled and the Multi-Dowel Sled kite was standing on its trailing
edge, about to take off.
kite a short distance from the ground, I carefully let it move out to
the full length of bridle. It felt a lot safer with the gloves on!
Soon, the line was out to 30 meters. The wind was obvious
stronger than the very light gusts of first outing. Hanging onto the 200
pound Dacron line was somewhat slippery using the gloves. I soon found
myself taking a wrap or 2 around a gloved hand whenever I wanted to
pause for a moment and watch the Sled climb a bit higher. With just
light to moderate strength wind, the huge Sled had no trouble pulling
line off the somewhat stiff garden hose reel. No fancy ball-bearings

The only way of managing the camera work was to put a turn of
line around my left foot. Just treading on it was not enough to prevent
line slipping out. At quite a pace sometimes!
After a while I decided to go to 60 meters of flying line, half
expecting a towing-point tape to fail at some point. All that was
holding the kite was 4 thin strips of packing tape. However, it didn't
happen. They are quite strong under tension, particularly when stuck
Since the tension in the line was getting uncomfortable, it
seemed the right time to find an anchor for the line. However, with the
reel pointing downwind, it wasn't straightforward to simply walk back to
a handy tree and wrap some line around it. I would need to get a whole
lot of slack line on the ground first. Conclusion - in future it might be
a good idea to always set up the reel a short distance upwind of
the intended anchor point! The reel itself is no good for this job,
since only a couple of tent pegs are holding it back. They could easily
While at 60 meters of line length, I paused for a while, to see
just how stable the Multi-Dowel Sled kite was during stronger gusts. Thermal
activity was evident by now, and some of it was quite strong. This had
me planning how I would keep the kite and flying line out of trouble if
something suddenly failed.
The bigger the kite, the bigger the variations in line tension it
seems. After all, a big kite will go right to almost zero tension while
it is floating down in a lull or copping a gust from behind. Then, the
tension can come back on very suddenly!
The huge Sled kite was proving very predictable, so it felt safe to try going to 90 meters. Mind you, I was still prepared to run up-wind or cross-wind in a hurry if necessary! Once there, at 90 meters, the thought did cross my mind 'how straightforward will it be to get the thing down from here?'
A bird zoomed past, higher and slightly downwind of the kite. This wasn't really a coincidence, since the bird was not flapping, and the kite was in rising air, pulling like an ox. At one point the Sled went directly overhead, and continued to pull line through my tightly gripped glove - taking meters of line off the stiff-running hose reel as it went!
Then, it was decided to go briefly up to 120 meters of line, before starting to take the big Sled down. The kite got to 350 feet alright, on 120 meters of line. But then I found that getting it down again was not going to be easy! To cut a long story short, I had to resort to taking double or triple wraps around each hand in turn, to get line in without slippage. This was awkward and slow. In future, it should be a lot easier to take the Multi-Dowel Sled kite down with the line properly anchored somewhere. Then, it's just a matter of walking out to the kite, effectively shifting the anchor point out to it as you go. Apparently, some like to tread on the line to do this, but that can't be very good for the flying line!
I know, how about a 50 pound de-power line attached to the top of the center spar. That would do the trick, wouldn't it! Just pull some tension onto it and watch the 2 Dowel Sled kite nose over, collapse and fall...
Bringing the kite in, things got a bit easier when it got under 50 feet of altitude. Finally, I started bringing the bridle lines together, hand over hand until the sail collapsed inwards and sank to the grass. I'd call it a very successful flight, despite a few awkward learning moments!
The Windtronic wind speed meter, which I reset after winds seemed to pick up a little, showed an average of 2.8 kph and a maximum of 7.5 kph near ground level. I'm itching to suspend it from the bridle line one day, to see what's really happening up there, but the thing is worth $100...
The story or stories above document actual flying experiences.
My write-ups are definitely warts-and-all since things don't always go totally as planned. However, half the fun of kiting is anticipating the perfect flight. When it happens, it's magic!
