I fitted a Stall Warner to the STBD wing. This mod is straightforward. A 10mm hole is drilled through the spar, and then a piece of weld wire is used to locate the position for the drilling of the hole in the leading edge of the wing. The tube is pushed through the holes and set in place with the template, all held in place with Redux. After curing the end is cut off and filled flat against the leading edge. The tubing is put through the spars to the wing root.
