Can someone explain how to do the mixer test on my Pulse (Pulse I 7m)? Also, what is the best setting for the mixer? I have been using this kite in
the buggy. I just like to cruise and am not looking for lift. I don't think that there is anything really wrong with how it is set now cause it
flies well, but I'd like to know more about tuning it to best suit my needs.

its a very long explaination..... too long to type out and lots of terminology.
best option is to download the manual from flysurfer.com / support

This is what is in the manual...
MIXER TEST:
The flying-lines (max. POWER/DEPOWER LINES-SYSTEM MPDL)
The flying –lines of the PULSE all consist of single pieces of 12, 6 and 3 meters. That way, you can reduce the line lengths in 3-meter-intervals from
21 m to 0 m.
All lines have been pre-stretched. Nevertheless, the depower-flying-line will become about 5 cm longer than the steering-lines, due to the higher load
when in flight. The trimming of the kite has been adjusted to this stretching of the depower-flying-line.
The so-called mixer is attached to the flying lines. It use the steering impulses of the front and back lines and steers the A-, B-, C- and Z- or
braking level.
The lines guided over the pulleys are wear and tear parts of course. These 150 cm spare part lines are made of special minimally pre-stretched
Dyneema, in order to to keep the shrink as small s possible. To achieve an optimal flight performance we recommend to implement the mixer test after
about 50 flight hours, to guarantee an optimal trim of the kite throughout the years.
To be able to control the trim of the PULSE you can easily apply the mixer test no matter where you are.
For this you have to fix the Front Main and Front Back lines at exactly the same length. Then you can control if A-, B-, C- and Z-Main end at the same
place under a load of about 5 kg.
The spare part line is overdimensioned by a factor of five. We recommend to exchange extremely worn spare part lines with original minimally
pre-stretched DNV500 lines. You can order these lines online at www.FLYSURFER.de or with your authorized dealer.
As soon as the mixer trim is realized successfully the flight performance of the kite is perfect again.
If there is a difference you can correct the length by moving the knot at the pulley of the B or C-Main Line. Before repeating the mixer test, you
have to pull the knot close with the full weight of your body to avoid it from moving.
If the B-Main or C-Main are too loong the PULSE becomes instable and might frontstall.
If the B-Main or C-Main are too short the PULSE might backstall.
....or is there something else that I am missing? I think that I mostly get it- I understand the ABC + Z lines and such, but I was hoping for some
tips or visual aids on execution. From this description it sound like all of the lengths should be equal? I see comments for other FS kites to set
the mixer with different lengths for the B and C lines....
Just wondering.... :tumble:

I am pretty sure that there is a video available at Flysurfer for this. Check it out. It helps to see it being done.

Archkiter, I think the newer Pulse2 manuals have better descriptions/pics.Keep in mind the Pulse2 uses a slightly different mixer though.I just mean
use the pics for reference.In general, if you fly at the coast(smooth winds) I'd stick with an even mixer as it delivers the fastest turning at the
cost of stability.
If you don't stress the kite much(buggy jumping) I'd get a set of "mixerballs" from a FS dealer and put them on. Makes tuning the mixer a lot easier
than the knots.Do one side at a time so you have a reference.There are threads on this subject on foilzone.
happy tinkering.

youtube has some videos on this subject too

thanks for the tips. videos cleared things up for me.
next question: any tips for undoing/ loosening the knots-it took me forever!
