To give tips what you could do and how. I attached the video for Sonic2, I don't know if video author Jussi is KF member so not sure if you can ask more here, but use Youtube comment or FB to contact him. And explain principles also in here as text.
Normal mixer tests etc, I already assumed these have been done dozen times by previous owner and by OP's text also by current owner, sure bar tip to trim lines even is todo task on long list of resetting everything to factory spec. That's why I started giving tips beyond "mixer test" if wing tips are loose/collapsing, uneven loading of bridle compared a1 to a12 might have uneven shrinkage and caused AoA change on wing tips, and also a1 relative to b1 and c1 changes behaviour. I though going bridle over relative each other is new thing to be done to the this kite instead of building all bridle from ground up what I understood from OP.Adventure Logs wrote: ↑Tue Apr 21, 2020 11:06 amNo PMAs or long mixer test on the Sonic2. It seems like you are willing to put in the work. What I would do...first bar test. Trimmed for full power, with bar fully sheeted in, all lines should be equal. Next mixer test, I bet she will backstall like a bitch and you’ll need to extend Z. If you get rid of the backstall but the wing tips are still collapsing/kite is tacoing, you can shorten b and c.
Any tips for knowing when to shorten z and when to lengthen it?
