We strongly recommend the use of epoxy laminating resin for all glued joints as it penetrates into the
narrowest of gaps, ensuring that joints are really strong. For some processes the resin should be
thickened with a thixotropic agent. Use coarse abrasive paper to roughen all areas of the fuselage
which are to be glued; the white surface of the pigmented parts must be sanded off completely to
ensure good adhesion. It is essential to use slow-setting epoxy for all joints involving the GRP
components; do
not
trust 5-minute epoxy.
Experienced builders may wish to deviate from the sequence of construction described in these
building instructions; this is left up to the discretion of the modeller.
Air intake rings
The intake rings (6) should be glued to the inside of
the motor pods. Apply epoxy only to the outer, round
edge; it is best to apply release agent to the inner
rounded face of the intake rings before applying the
glue, as any excess resin can then be filed off easily,
producing a smooth surface on the inner face of the
intake rings (6).
Glue the ducted fan units in the recess of the intake
rings (6), working from the inside of the motor pods,
then install the motors and connect the cables.
Cut out the nozzle (14) from the film supplied, and stick it to the mantle ring of the ducted fan unit from
the rear using adhesive tape.
Seal the underside of the motor pods by attaching the pod hatches (13) with adhesive tape.
