sure that the joiner bags and the joiner fit into the recess easily but without
movement.
Next clue the prepared carbon strips in the milled channels
of the main wing panel. For this you best use epoxy or a
low viscosity super-glue.
Before you glue (Epoxy) the joiner bags and
the joiner into the main wing panel you have
to sand (120 grit sandpaper) both parts
slightly to assure a proper bond. In addition
close the joiner bag on the end which is glued
into the main wing panel with some modelling
clay (Play-Doh 'borrowed' from your kid works
as well) or wax to avoid epoxy running into it.
Now glue (epoxy!) the joiner bags into the
main wing panel. Make sure that the joiner
bag has good contact with the balsa (left- and
right-side) as well as the carbon strips (top and
bottom).
Now clue the carbon strips (as you have done
with the main wing panel) in both inner tips.
For the next steps we don't recommend to do both sides in parallel.
Give the joiners on the side which will be glued into the tip a light sanding to
(120 grit sanding paper) to get a proper bond when gluing them into the tip.
Slide the joiner into the joiner bag of the main wing panel). Now put some
Epoxy into the cut out slot of the tip and slide the tip onto the joiner. There
shouldn't be a gap now between the main wing panel and the tip (
Do a 'dry fit'
in advance
) . To assure the proper dihedral lay a 44mm balsa block under the
end of the tip and let the Epoxy cure. Repeat the steps for the other side.
