For the complete discussion on the diabolical problems associated with "resetting the mixer", "compensating for line shrinkage", "adjusting the adjuster", adjusting lines "C", "B", & "Z", & trying to stop RAM AIRS from back stalling, check out: viewtopic.php?f=1&t=2378918&p=778491#p778491gmb13 wrote:I am assuming a few things:plummet wrote:Hey bro's.

Is it simply a matter of lengthening the rearlines or shortening the front?
Should I lengthen the Z line abit?
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.

After several weeks of use, ram air bridles typically stretch and deform, further compromising aerodynamic performance: viewtopic.php?f=1&t=2358958&start=0Kamikuza wrote:Have you done a mixer test and checked your SPL length?

Alternatively, you could just trade-in your flying sleeping bag for an inflatable and save yourself the trouble.

That's only the case in kites where the bar solely controls AoA though . . .
