I am working on a Kelly D project (Rotec R3600 engine) -- my question is on the installation of the aluminum leading edge of the wings which are wood with 1/4 inch plywood ribs. On the Biplane Forum some months ago I saw comments about the aluminum warping when the plane was parked in the sun -- the solution to that was to install the edge in approximate 3 foot pieces so it could move some. I am after to any suggestions/installation procedures that have worked for you guys. If it's installed in pieces, how is the lap configured, etc. Any comments would be appreciated.

Thanks, Stan
