I don't know if it is reasonable to try to guess how big tensions different line rows have. I meant how much relatively different line rows must be pulled, to get fastest upwing. Like it is discussed earlier, this depends how much force kiter is able to use/how strong the wind is. Compared to original setup pulling more B-C does not improve upwind, because it lowers the camber. In original system camber usually slightly increases when AoA increases, it is usually the best for the upwind and generally too.foilholio wrote:Best upwind is with it lightly tensioned while B and C have more tension.
If you tighten very grossly brakes, B-C line rows do not function almost at all. Then kite is when powered in "high-camber-with flaps" setup. When sheeted in it generates quite a lot power, sheeted a bit more it stalls aggressively. It is so obviously wrong that I've not even tried to use setup like it more than for awhile.foilholio wrote:This I have not so noticed maybe you mean it is less stable?
Yes, no need to argue.foilholio wrote:Lift will be lost but L/D can improve. Didn't we discuss this before?
No. It is very well possible to change AoA of the foilkite without any shape distorsions. Then camber stays the same. However it is observed it is beneficial to increase slightly camber when AoA is higher, even though some distortions are produced.foilholio wrote:True but they all fold at some point.
Folds are seen when some linerow (B-C) is tighter/looser it should be. Of course if brakes are too tight they produce a fold somewhere in between C-Z. Some small fold is however tolerable when fully sheeted in, how much is a bit matter of taste. Trend is to towards conservative brake tightness, because if too tight too much drag is produced.
If brakes are loose, it kicks in later when sheeted in - however always 1:1. If tighter, then B-C comes later. Just two different views for the same matter, no need to argue here.foilholio wrote:Big incorrect there. They all interrelated i.e. tension one it loosens the other.
Of course. But there is limited possibilities to change pulley ratios (if not use one method I've tried years ago). Line row locations instead are quite freely choosable.foilholio wrote:Nope both can affect it.
