The canopy
Whether you are building the ASW 28 with or without a retractable motor, you need
to drill a 10 mm Ø hole in the point of the fuselage nose.
The hole is required for gluing the front canopy locating peg to the fuselage.
Glue is applied to the correct point in the fuselage through this hole in order to fix the
front locating peg in place.
Drill a 2 mm Ø hole in the front of the fuselage canopy flange, as shown in the photo.
Place the canopy in its recess, and check that it is a snug fit all round. Now slip a
length of 2 mm Ø steel rod through the front 10 mm Ø hole in order to mark the posi-
tion of the hole on the canopy frame. Remove the canopy and bore a 2 mm Ø hole in
the frame at the marked point, drilling to a depth of about 4 mm. Slip a length of 2
mm Ø steel rod through the 10 mm Ø hole in the fuselage nose and through the hole
in the fuselage flange, so that it engages in the 4 mm deep hole in the canopy frame.
Tape the canopy to the fuselage in this position, so that it cannot shift on the fuse-
lage. Working through the hole in the nose, apply glue to the steel rod where it meets
the fuselage; this is best accomplished using a syringe with a length of aluminium
tube as an extension. Allow the glue to set hard, then remove the canopy from the
fuselage once more. The next step is to install the canopy latch, but the method dif-
fers according to the version of the model you are building: glider or powered version.
For the glider version drill a 3 mm Ø hole below the wing root fair-ing on one side,
and another in the rear canopy flange, as shown in the photo. Fit a 3.2 mm Ø plastic
sleeve through these two holes, projecting at the front by at least 5 mm. The plastic
sleeve can now be glued to the inside of the fuselage. When the glue has set hard,
trim the sleeve off flush with the fuselage.
