Tail struts/rigging--RF interference???
Just a suggestion.....
Try Spider Line, fishing line.... (ala, Kevlar)
I use 60lb for pull, pull rudder and for tail bracing all the time..
Local fishing supply stores should have it..
The heaviest I can find here is 60lb...
But ya can do a serch for "Fire Line, Rip Cord" and get it in the 100lb flavor...
Best advantage is no metal to metal bugs...is thin, and strong...
