Fitting the wings, tailplane and fin
Steps 63 to 65
•
Take the parts for the wing struts from the basswood sheet and attach the
forked ends with micro screws
•
Fit the wings to the fuselage. You may need to gently sand the tabs on the
fuselage to get a flush fit.
Glue the wings in place over the tabs using a slower drying glue to give time
to slide into place.
•
Attach the middle of each strut to the tab at each side of the fuselage
alongside the cockpit
•
Fit the forked ends onto the spars butting against the second rib and glue in
place.
•
Glue the fin to the tailplane at right angles and with the rear edges in line.
•
Fit the hinges between the tailplane and elevator and glue carefully, leaving a
small gap between them and slipping some pieces of polythene between so
they don’t become glued together.
•
Fit the rudder in the same way.
•
Fit the control horns to the rudder and elevators
•
Glue the assembly to the rear of the fuselage making sure the tailplane is
absolutely level in relation to the wings
Steps 66 to 69
•
Make up the engine mount from the 6 basswood pieces shown
•
Firstly, laminate the 2 forked pieces together so that they are exactly aligned
•
Glue these carefully into the 2 larger of the remaining pieces, making a left
and right assembly. Make sure the outer parts of the forks are fully home and
the parts are at right angles
•
Glue this assembly into the 2 smaller pieces, again ensuring they are at right
angles to the sides and level with each other.
•
The completed assembly should be attached with micro screws under front of
the top deck of the fuselage with the fork pointing forwards.
•
Make up the motor assembly by sliding the motor into the plastic mount so
that the gear on the motor engages with the large gear.
•
Fit the propeller to the shaft protruding through the large gear.
•
The plastic assembly has a hole above the rear of the motor, this slides over
the centre tine on the motor mount
