Bevel the hinged control surfaces (ailerons, rudder, & elevator) along the bottom edge of the
ailerons and elevator and down the left side of the rudder, using steel rulers and fresh single-edge
razor blades. Set a 12-inch or longer metal ruler backing at the edge of your workbench. Lay the
foam part to be beveled on the ruler, aligning the edge of the ruled and the edge of the foam
nearest to you. Lay a second steel ruler facing down far enough back to expose enough foam to
allow a 45 degree slice to be removed. Cut the foam with the single-edge razor blade held against
both rulers. Angling the blade makes a smoother cut.
EPP foam dulls blades surprisingly fast, so be prepared to change to a fresh blade when you detect
snagging or excess drag as you make your cuts!
