RE: Skymaster F-15 construction
Dan,
One problem I had in mine...see those holes in the former in the front section of your plane? Thats the former your retract mounts to. Dont know why they would put holes in a high stress former. I recommend laminating that too with some thicker ply especially while there is nothing else in there. All it takes is one hard landing or a landing with no nosewheel (which was my case) and it will crack that former between the holes.
