Kite Power No Tower

I have one jumbo power sled 36 joker lift kite and had problems yesterday with it flying erratically in a chaotic wind field.

Attaching to spread anchored tethers and cross linking the bridling to the tether arch allowed me to greatly stabilise flight and maintain good lift.

I’ve probably read that description of how to solve the problem before…
But here’s the video

OK, yesterday got a bit hairy scary. This was Daisy 3’s toughest test yet.
The back of my parents house has a terrible wind field for a kite flying. A small patch of grass crowns a small steep hill covered in pine trees and granite.
The wind was super gusty because it rolls off much larger hills close by. The strongest wind I have yet tested in.
Perfect for kite survival testing. Turns out to be a good human survival test site too.

I thought I’d be smart and do the test alone. (?) The test plan was to fly Daisy 3 further downwind, underneath the lifter tether, suspending the Daisy 3 lift line from a point high on the lifter tether. But I was rushing to show off to the ferry passengers who would be going past in 5 minutes.
Things quickly went wrong when I thought I should fly the lifter on a long single tether; to avoid the down draft over the hill… oops! This meant spare tether line loose at the top of the hill at launch time. I imagined a “clean” launch and flight. Wrong! It was far too windy for that! I knew the dangers but stupidity and bravery took over. During launching as I paid out a little tether, the lift kite swung and yanked wildly. Did I have my gloves on? no doh! It was all I could do to wrestle the lift kite back down away from the wee cliff edge.

Still not being to overly bright, I re-rigged a single shorter tether. Now I could launch safely. Ah but the flight was hugely erratic. (Peter Lynn describes why)
With a bit of safety in mind. I rigged a wide split dual tether. Lines at about 110 degrees arc. Stability improved a bit but the kite was still surging and swaying ~40 deg from average downwind.
I attached the lift line which gave a further slight steadying influence.
I should have also split the lift line, bridled it onto the two tether lines… but instead I attached directly to the lifer kite bridle point.

I carried on and hoisted the back end of Daisy 3 sufficiently to start spinning… Blimey was it ever going round fast. Good power against the brake. Sometimes with wind shifts it seemed to be pointing near vertically. But it was a short test. Around 5 mins of battling Human VS wind. I had rigged the lift line poorly with no good way of cleating and flying single handedly. I was holding the lift line end in my braking hand.

The wind won in the end. I was quickly knackered. This was a high intensity sport test. An even shorter 2nd test, was followed by the start of a third. When I noticed the same T piece shear fracture as had happened previously had now happened to another old design T piece. Test over pack away. First sensible decision of the day.

I need to move to a more stable lift platform. KPower style.
Possibly going to cooperate with skybums on this.
