I had one in the early 90's and did the Nyrod number. If I did it again, I would use Central Hobbies carbon fiber rods and rod ends and go control horn to control horn direct. These rods are stiff. That's what I did on my Heckler and works great!
Good landings!

Oh, FYI. Flair Models put out a kit for the Stickit IV in the 90's.
