Before separating the ailerons, drill for the hinges. I prefer to use Robart hinge points, excellent hinges and as you can see dead simple to get the holes drilled and aligned, I have also added some extra wood at the hinge point so there is more material for the hinge to bite on.
There is a small issue on the plan, its impossible to get the aileron contol run square, the aileron horn is outside the servo well, its only a few mm, but not ideal.This is shown on the plan, with the control run at a slight angle.
I have added an additional sub rib to move the horn inside the servo well.
Looking at the center picture youcan see how a light spray even outs the wood colour to help the look after covering.
