In post [ANNOUNCEMENT] Schweizer SGS 2-33A Glider (Freeware) - #21 by EPPRglider81 I already described you how you can fix connection points for Ka7 yourself.
I can assure you all unofficial gliders will soon be adjusted to new glider tow and other mechanics introduced in SU11, sadly SU11Beta didn’t release any info or example glider for devs to have time to adjust so some time now is needed.
I don’t think hiding tow cable functionality is necessary.
