Clecoed the elevator together and checked for trueness and it was within limits, about 2 mm gap under l/h trailing edge. Installed the trim tab to the elevator being careful to build it true. When installing the servo, I decided to add an L angle to the left side to spread the load and stop the skin distorting. Drilled everything out to final size.
lookin the business
notice the line of clecoes to the left of the servo gripping an L ange inside to stop skin distortion
