As most foilkiter know, foilkites allow to change / adapt / correct the camber profile of the kite by playing with the speed system ; you can play on either various main briddles (A, B, C or Z) to do so . I drawn some illustration to show the various impacts of main possible modification as follows :
Extend A: => decrease cambre profile but not homogenous
Shorten Z: => increase cambre profile and homogenous (similar as C and 1/2 B modification like Flysurfer C changing)
Shorten A: => increase cambre profile but not homogenous
Shorten SPL C: => decrease cambre profile and homogenous (similar as C and 1/2 B modification like Flysurfer C changing)
Extend SPL C: => increase cambre profile and homogenous (similar as C and 1/2 B modification like Flysurfer C changing)
I also try to show that you need to bring A and Z back to same elevation (using the trim or bar sheeting) to be able to compare the camber profiles.
To gain power for low end I recommend Case 5 (Extend SPL C) or Case 2 (Shorten Z + trim the clamcleat a bit)
To avoid frontstall instabilities I recommend to use case 4 (shorten SPL C) or "reverse Case 2" (=extend Z and untrim the clamcleat a bit );
Took me some hours but I hope this is understandable (and useful for some of you) .
