I'd like to make my speed 3 less stally. Apart from resetting the mixer what else do you recommend?
is it simply a matter of lengthening the rearlines or shortening the front?
should I lengthen the Z line abit?
I am assuming a few things:
1) You have reset the mixer to 0
2) You have compensated for Back line shrinkage by shortening your front lines using the Black Line above the adjuster. Front and Back lines should be the same length when the Adjuster is fully open and the bar is pulled all the way down to the chicken loop. Best to tie up the end of the lines to a tree or other solid stationary object to test this.
So. If the kite is still to backstally, try lengthening C. B will adjust itself harmonically by itself. This will sacrifice a bit of stability, but will give you less backstall. Lengthing Z will just make the kite turn slower and will also reduce the Low end of the kite.
