All of the parts are out of the box and the covering looked great.
These are the additional components needed to complete the Sport GP/EP ARF.
already glued in place, but give them a
tug to be sure they are secure, as were
mine. Use CA adhesive to reinforce
the mounting holes after you’ve drilled
The aileron horns do not employ
backplates so the screws must be
secured to the wood. Clevises and
right-angle bends with keepers secure
the control rods in the usual fashion.
The preformed landing gear must
be installed so that it angles back
toward the wing’s trailing edge. The
inset keeper slots are a nice feature;
everything is flush with the wing’s
surface. The wing panels are joined
with an alignment pin and spar joiner
using 30-minute epoxy.
The fuselage is next and it goes
together quickly. If you plan to use
electric power, there are cooling air
exit holes in the bottom that should be
opened and the covering sealed with
Next epoxy the horizontal and
vertical stabilizers in place. That can be
done as a single assembly or separately,
but if you choose the latter, be sure
to prevent glue from getting into the
vertical stabilizer slots. Ensure that
everything is square with the wing
before final gluing.
After that is complete, install the
pushrods into the preinstalled guides
and fit them to length with the horns.
The tail control horns use a backplate,
so you’ll drill those holes all the way
through and harden them with CA
