instant adhesive and then bond it to the canopy with one or more layers of fibreglass cloth
(160 g) suitably treated with epoxy resin.
Strips of self-adhesive felt may be installed along the inside edge of the canopy to
complete the job.
Tip. Work carefully and accurately. Your patience will be rewarded by a tight fitting
canopy!

Installing the all-flying tail-plane.

CAUTION! The elevator bell-crank mechanism is pre-installed in the fuselage, but is
yet to be permanently glued into place.
Attach the all-flying tail-plane making sure that the rearward steel wire joiner passes
through the hole in the bell-crank installed the fin. Carefully check the alignment of the tail-
plane halves with the fin.
Prepare a means to hold the fuselage with the fin at right angles to the work surface. Also
prepare something on which to support the two tail-plane halves at right-angles to the fin
and at the correct height. A few carefully selected books and/or Compact Disc holders
might well serve as an adequate jig for this purpose.
Now loosen the two Aluminium nuts holding the bell-crank bearing in place and make any
adjustment necessary to ensure that that tail-plane halves can be aligned at exactly 90° to
the fin. Apply a little thickened epoxy to the inside of the two nuts and carefully tighten,
constantly checking that correct alignment between tail-plane and fin is maintained at all
times.
Leave the entire tail-plane assembled in the jig described above until the adhesive has
fully cured.
Tip: While working with adhesives in this area apply thin parcel tape over the sides of
the fin in the area of the bearing and cut through the tape to expose the holes. This
will ensure that any excess adhesive does not spoil the finish on the fuselage.
