I Cut a peace of balsa from ¼ in scrap stock and inserted it between the flap servo mounting rails. I want this wood to press fit between the rails and don’t want to spend hours getting it to fit right because its only purpose is to give me something to tack the covering too. So I cut the soft balsa 1/16in longer than it needed to be. Then cut 1/16 deep wedges out of each end vertically and horizontally ( if any one wants a pic of this let me know). Then puss it into place carefully (a slip here causes a tear in the covering) the v’s we cut in the ends will aloe the wood to fit into place with some pressure. If you think the pressure is to much cut more v’s.

I installed the aileron servos because I plan to install the “Y” harnesses before installing the flaps, infact I’ll probably install the airlines and retracts before I button it up because I have access.

Now to start installing the flaps I need to make room for the end caps for the TE of the wing and the LE of the flaps. The end caps will be made of 1/8 balsa with the grain running span wise. It is not intended to be a stress bearing member but rather as shear webbing between the little bit if sheeting I left on the top and bottom of the wing. I widdled the ends of the ribs back into the wing so they would fit the end caps.

I plan to use robart hinges here so behind the end caps I’ll install some ¼ in balas for a good mount I’ll go into more dept as I do it. One note here the ribs are not evenly spaces and some are not mounted parallel so each hinge mount will have to be fit individually. So it will go slowly
