Installed the flap on left wing. Secured each end of the flap hinge to the wing skin and flap brace with a cleco side clamp. Set the aileron to neutral and adjusted the flap to give a ¼” gap between flap and aileron. Adjusted the flap height to align the trailing edge with the trailing edge of the aileron. Streched a string from outboard end of aileron to inboard end of flap. Everything looks to be in alignment. Moment of truth—drilled first hole thru skin, brace and hinge at the outboard end of flap. Checked alignment with aileron—flap had dropped about 1/64”. Moved it back into alignment and drilled a second hole. Alignment looks good—drilled a few more. Checked alignment and flap was again about 1/64” lower than aileron. Not sure how this happened, but suppose I will live with it. Drilled the rest of the holes, clecoing each after drilling. After all drilled and clecoed, checked movement and flap works very smoothly. The alignment between trailing edges is not visible to the eye, but it is there none the less. Overall, I am happy to have one flap mounted.
