rib (not the tip of the wing). The dope will sink through the
tissue and attach it to the wing.
Pull this area until it is nearly wrinkle free. You can loosen it
with a brush and thin nitrate if you see an obvious wrinkle.
Attach the tissue to the outside perimeter of the LEs, TEs,
and the end ribs, giving the tissue a smooth appearance. You
don’t need to attach it to each rib at this time because the first
coat of clear dope will do that.
Cut a section of tissue to cover the area from the tip rib
to the tip itself. This needs covered separately because tissue
does not cover smoothly on a compound surface. Again, get
the tissue as smooth as possible, but not drum tight. Cover
the bottom in the same manner.
You have now covered the top and bottom of one half of
the wing. Carefully trim off the overlapping tissue with a
double-edge razor. Using a fine atomizer, lightly spray the
top and bottom of the wing with water. Some builders use a
mixture of water and alcohol, but I prefer water.
While it is wet, place the wing in a jig of raised 1/8-inch
square stock and pin the wing down to prevent warps
until it dries. You may want to give the wing’s TE a 1/16-
inch washout. To pin it down, I slant the angle of the pins
rather than pierce the balsa.
Cover the other half of the wing using the same
process. After drying, paint the wings with three coats of
thin nitrate dope, each time placing the wings back in
the jig to avoid warps.
Cover the tail and the fuselage, making sure the grain
runs lengthwise and remembering that tissue does not do
well on compound curves. Place the tail surfaces in a drying jig.
The fuselage needs no jig for drying, but the RC components
and control rod placement need to be determined for proper
access and balance before covering the fuselage and the center
of the wing.
Cover the cowling with tissue and sand lightly between coats
of nitrate. If an area needs sealer-type filler, you can mix some
baby powder with the nitrate dope, but not on the open areas
