This looks like the place for this.
My last few control line stunt type airplane are done this way, so far I like it.
Cures a few problems
1--The old Dang it,knocked the rudder off on the car door
2- adjustable
3-Easy
4-holds adjustment with "normal" bumping and abuse.
Made from .030 soft aluminum.
Measure offset with strait edge on inside of fin to check setting if bumped.
Regular R/C type hinge slots.
Pictures are of light weight Shoestring practice/fun plane.
Looks like All up weight will be 23-24oz with fox stunt.
