Tjena Janne,
What strenght fishing wire are you using for what size plane. Are you just making sure that the wire is stronger than the strenght of the servo? The Dubro pull-pull system comes with plastic coated wire. I don't really see the point in having a coated wire but perhaps someone else here might know the benefit? ...unless it is to prevent corrosion?
By the way Jan, I have got myself another Extra kit and are truly enjoying the build. I guess you will see it at the field when finished.
