I'm looking for some advice. I'm building a balsa wing to replace a Styrofoam wing on an areobatic plane. The original bellcrank will be used. The bellcrank has 3 1/16" leadout wire to leadout wire holes. The original symetrical wing has a plastic guide attached to the wingtip which is 1" wide with six wire guide holes spaced 3/16 " apart. The exit guide is located at the thickest part of the airfoil. I know from reading web articles about this aircraft that the pilots have had greater and lesser success utilizing different exit wire guide holes. It's not clear to me why. It is also not clear to me why I don't just match my wingtip exit holes to the bellcrank holes. That is, two parallel lead out wires. I plan on running the leadout wires through aluminum tubing tp prevent wear and tear on the balsa ribs and to make leadout wire replacement easier. I'm a novice and probably would not appreicate different wire spacing anyway. Any suggestions?
