Materials required:
Epoxy resin and flock
Fit the wing tips
If you intend to fit strobe lights to the wingtips, drill a hole in the wing root and use a long rod
to route the strobe wiring along behind the leading edge and out of the wing root. The wiring
will need to be routed out through the strobe mount before fitting the wingtips.
With the wing inverted pre-fit the wing tip to the end of the wing and make sure that the tip
sits firmly over the wing and that the leading edge of the tip is level with the leading edge of
the wing.
Make adjustments as required – some material may need to be removed from inside the very
front of the wing tip. The wing tip should fit up hard against the joggle step.
Tape in place and turn the wing right side up. The rear of the wingtip has a step that sits into
an aligning joggle at the top rear of the wing, circled in the photo above right.
Hold the wing tip in position and fix in place with 6G self-tapping screws, then remove the
wing tip. Remove the peel cloth from the inside of the wingtip and sand all of the surfaces to
be joined.
Mix a batch of resin and coat the surfaces then add flock to the remainder. Apply a 2mm layer
of flock to the wing and fit the wing tip into place: hold the wing tip slightly open as you
place it over the end of the wing and then let the wing tip close onto the wing so that the flock
is not pushed ahead of the wing tip. Fix in place with the 6G self-tapping screws.
Wipe away any excess flock with a clean mixing stick and leave overnight to cure.
Next day remove the self-tapping screws – apply heat if required to loosen the screws.
