I have a few foil kites but need something big as it is coming in to winter here and ideally i wanted something lower aspect than my race kites (R1s) so I can run longer lines and will be using this kite in fading/sketchy winds. A friend offered to sell me his Halo 19m cheap as he bought it last year for similar reasons and was learning foil kites and hydrofoil, and the kite had a beating and many swims and was used overpowered many times. So the kite went from flying very well to at the end of the season not flying properly at all so he offered me the kite cheap and I bought it. The problem is the kite has a fixed bridle with no adjust-ability, and there are no line plans for the bridle showing the line lengths (I asked the F-One dealer in my country for help and he said No as the kite wasn't purchased in this country). I have seen my friend try to fly the kite and it is definitely badly out of tune to the point it can't be used as it currently is.
So I picked up the kite and the first thing I tried was a long mixer test to see the air-foil shape at various sheeting positions. The result was that it looks like B and C (and probably Z) have shrunk massively from where I think they were originally. The manual recommends a short mixer test (and to change A level if short mixer is out) so I checked that and the short mixer test comes up ok. The problem seems to be that the very long thin bridles have shrunk a lot. So I guess there are two schools of thought on tuning (from what i can see) one is that you can zero the short mixer and stretch the bridle back to where it should be/was originally, and the other is you can change the mixer to lengthen B and C levels (and Z to match change of C). As I don't have line plans I have no idea where to stretch the bridle lines back to, also this seems like an easy way to mess up by having some bridle lines at various states of shrink/stretch and could end up in a mess. So I have opted to lengthen C and B (and Z same amount as C) to a point where the long mixer test lengths seem to make the appropriate shape for the wing - based on other kites that are similar and the relative lengths of their lengths from pigtails to A1, B1, C1. After lengthening the C pulley line in the mixer (using a new spliced section of line) it seems the long mixer shape lines up much better at the normal sheeting positions so I'll see if that helps the kite fly more like it used to before the bridle shrunk. But am I on the right track?? If I had a line plan things might be easier.
Any advice or help, especially from anyone who has adjusted a Halo or similar before would be great appreciated. Thanks.
