I'm building a TF Corsair and am using Robart hinge points as well as rounding the leading edge of the control surfaces. I want to use a strip of 1/64 lite ply to overlap the gap by about 1/2 cm to give it a better scale look. I have already sanded down the balsa to have the ply flush with the top of the stab. My question is how to best orient the grain of the 1/64 ply? If I run the grain parallel to the seam will it curl down or up? Should the grain be perpendicular to the seam for more strength. Thanks, Pete
