I've been working on the fuselage and ran into a challenge or two. The elevator is moved by a "Y" shaped pushrod. The diagram in the construction manual shows the assembled pushrod which is made from a hard balsa stick and wire ends, the trick is bending the ends at the correct angle. The diagram shows only the horizontal length only not the length of the bent wire so I approximated the angle between and with a little math determined the length of the bent sections. It does show the exact exit holes for the pushrods and I drilled the holes. Since the pushrod assembly is already bent, it required some doing to get it through the holes. I had some antenna tubing and fed those through the holes first and eventually got them through the bulkheads to the servo bay. Then I inserted the ends of the pushrods into the tubing. As I fed the pushrod back the tubing would guide the ends through the bulkheads and eventually out of the holes. It worked great.
