RE: Hangar 9 33% Edge 540 - Part 3
Al,
Usually, the local hobby shops will carry SIG or Midwest brands. Tower hobbies sells the aircraft grade 1/8" birch plywood [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXAS64&P=7]here[/link]. We glued two layers of 1/8" together for 10 ply which is stronger than the 5 ply 1/4" plywood.
