Mini Bossanova - Instructions
STEP 07
Carefully mark the tailplane on the top and bottom where it enters the fuselage using
a soft, water-soluble felt tip pen. Now remove the tailplane.
STEP 08
Cut away the covering from just inside the marked lines to give a
film-free surface for the glue to bond on the top and the bottom of
the tailplane.
IMPORTANT NOTE: Ensure that only the film is cut - not
the tailplane - as this will seriously weaken the structure.
STEP 09
Locate the four elevator hinges (two each side) and insert them half way into the pre-
cut slots. Using thin cyano, pour a couple of drops onto each hinge - above and below
- ensuring the glue soaks into the hinge and the surrounding wood.
STEP 10
Locate the bent wire elevator joiner and place it in the rear of the
tailplane slot in the fuselage. VERY IMPORTANT: Do not omit
this step as it will be almost impossible to fit it after the
tailplane has been glued in position. Now glue the tailplane
in position using epoxy, checking that it is correctly aligned and square
to the fuselage and wing seat. You may wish to use masking tape to
protect the covering whilst you do this (removing it as soon as you are
satisfied with the alignment and before the epoxy cures). Any excess
epoxy can be wiped from the model before it cures using methylated
spirit or methanol.
STEP 11
Once the glue has thoroughly cured, the elevators can be fitted. Apply
a small quantity of 5 minute epoxy to the elevator joiner as shown.
Now slide the elevator onto the wire joiner and ensure that both
hinges enter the pre-cut slots in the elevator. Ensuring a gap-free hinge
line, add a couple of drops of thin cyano to the top and bottom of each
hinge ensuring that the glue does not run through the hinge line onto
the bottom of the tail. Turn the model over and drop more cyano onto
each hinge from the other side. Repeat for the second elevator half.
STEP 12
Once the epoxy has cured, flex the elevators to ensure that they move
freely through their entire range of travel.
