.
METHOD 1:
1. Coat the wing center joint with slow-
drying epoxy glue.
2. Lay the tape on top of the glue.
3. Holding one end of the tape so it won't
slip, "squeegee" the glue through the
tape with a small paddle of scrap balsa.
Scrape over the tape several times with
the paddle to smooth the tape and
remove any excess glue.
4. When dry, sand lightly to remove any
rough spots. Try not to sand into the
fiberglass tape itself.
METHOD 2: (Shown in the photo)
1. Cut the tape to length, then lightly spray one side with a spray
adhesive (such as 3M "77").
2. Position the tape on the wing center joint.
3. Soak the tape with thin CA. The spray adhesive simply holds
the tape in place - it won't affect the strength of the CA. A
second coat of CA will help fill in the weave of the fiberglass,
resulting in a smoother surface. Rub the second coat with your
finger (protected with plastic wrap - keep it moving!) to smooth
out the glue. Use a fan to keep the CA fumes away from your
face.
4. When dry, sand lightly to remove any rough spots. Try not to
sand into the fiberglass tape itself.
Ailerons
23.
Sand the trailing edge of the aileron round and bevel the front using a sanding block. A pencil line drawn down the center
will keep the bevel symmetrical.
24.
Position the aileron on the back of the
wing, leaving a 1/32" gap between the
inboard end of the aileron and the
outboard end of the torque rod block.
Mark the location for the torque rod
installation. Slot and drill the aileron
leading edge to receive the torque rod
wire.
25.
Trial fit the aileron to the torque rod. Once it fits, temporarily tape the aileron in place and sand the outboard end flush with
the wingtip.
