No doubt a kite that weighs less helps quite a lot. One strut LEI flies sooner than a many strut LEI. No struts are lighter still. Foil kites have a better efficiency than the no struts but wider and slower turn.kitexpert wrote: This must be called pilot incapability, lack of try or BS. Problem is not to get kite in the air but to develop enough power to get going without losing ground. Looping kite constantly and dragging yourself slowly downwind is possible in lightest of winds but it doesn't make much sense.
Low weight does not make kite any bigger or make it pull more. For design point of view making kite from lighter material is trivial, no amount of CAD can help that. If 12m kite weights 132g more or less isn't very interesting.
10 knots is force 3. 6 knots is force 2. I start to consider flying tube kites at 12 knots. I can go lower but is less fun.
Yes lighter is better, no one denies that but question is how significant differences are. At least some 132g for 12m kite is not worth mentioning. For dynamic benefit you must calculate weight differencies for complete weight of kite, including weight of the air inside. And is lighter with lower L/D better?jakemoore wrote: ↑Tue Feb 05, 2019 7:10 pm10 knots is force 3. 6 knots is force 2. I start to consider flying tube kites at 12 knots.

Yes a kite that pulls harder can lift in lighter wind.
At minimum, lighter wing loading makes a bigger kite practical. My experience is there is a difference, in pull especially at the light air. Less force from gravity allows the kite to rise to zenith faster and a better loop for power. Less kite weight and line tension required to keep the kite in the air allows deeper downwind angles.
Then there are the lulls and moments when line tension is lost bobbing up and down in shore break while dragging deep enough to waterstart. Yes I have done kite 360 running in a circle in zero wind with Flysurfer Psycho 1 12.5m. It’s exhausting but was a functioning alternative to the 24M C kites of its era. Good luck running upwind in ankle deep snow.
Indoor kites are above all light. No doubt the Soul is a marvel of engineering and design. Soul in 15m is 840g or 30% heavier than the lightest Pulsion. How much would a cyclist pay to shave 840g off a 9 kg bike. I wish the problem of weight was trivial enough to have more contenders in Force 2.
Maybe the improved L/D from single-skin to Pulsion is what allows the kite to stay in the air just a fraction sooner. Just for the purpose of having numerical discipline, the difference between Soul 12 (FS reported 2340 g) and Pulsion 12 27g (Regis reported 1618 g) is 722g. Thats slightly more than a pair of size 44 Birkenstock Milanos. I suspect hanging my sandals off your heavy Nitro2 or stuffing them into the vents of Soul or Pulsion will have a noticeable effect on how the kite flies in force 2 and 3 winds.kitexpert wrote: ↑Wed Feb 06, 2019 1:34 amYes lighter is better, no one denies that but question is how significant differences are.

I have some experiences in Force 2 winds with hydrofoil and premium brand normal cloth medium-high aspect foil kites. This is Force 2 at kite level, based on riding next to a limp flag on a pole attached to a pier at kite level. The flag is only 75 meters downwind of the flying kite and a enjoys few mile fetch of clean wind over the bay. I don't think I can go below 6 knots and usually I want to see 7-8 knots on our iKite sensors to drive to the launch. But at this low end, I am not limited by the impulse of the looped kite on long lines to bring me up on to the board and then up onto foil. The limiting factor is keeping the kite in the air while I access deep water that is upwind of me. Actively flying the kite while trying to body drag or even swim upwind would serve only to drag me back to the shallows.kitexpert wrote: ↑Wed Feb 06, 2019 1:34 amIn 6kn there is only a fraction of kinetic energy available compared to 10kn, precisely 36%. This is the energy what kiter uses for traction. For similar kites to achieve same pull it would mean to have almost three times as big kite. Many don't want to accept this and they continue to give unrealistic low end wind speeds for their kiting. In reality explanation is measurement error or wind gradient or both.
There won't be much competition in 6kn wind speed category. To order kite from light weight material is trivial but it will be costly and kite will be fragile. Then you can struggle with risk for self rescue and do lame kiting perhaps in 1kn lower wind than before
Alas our local Soul riders don't come to the launch in wind I consider to be light. Yes the Soul is a jumper. There is good video evidence of Soul performing in light wind but our local Soul riders are more interested in boosting. Those guys fly quite high in 12-15 knots on shorter lines and its amazing to see. I usually have my 7m in the air when they are out. I would like to fly the Soul in light wind.kitexpert wrote: ↑Wed Feb 06, 2019 1:34 amSoul is more efficient kite than Pulsion because it has less drag and very probably also more lift. This means higher L/D which means more pull, more jump height, more hang time, higher speed through the WW and more powerful loop and better upwind ability. If kiter knows how to fly his kite high L/D is also very beneficial for lightest winds, then it is possible to fly actively and to get more apparent wind which is of course essential.
VMG is 50% more expensive than Soul. Soul costs a little more than Pulsion. And they all cost a lot more than Pansh.
