Upper tri stock in place. Note 5/16 tri on transom.
Acid brush bent for “all up and under”.
Tub top in place. Note that it is centered on radio box lip.
Fit and glue the balsa tri stock to the top
of the tub sides. Try to get them flush, or
slightly above the sides.
Use epoxy finishing resin (or West
Systems epoxy) to seal the inside of the
tub. Be sure to seal around the boom
tube sleeves, pushrod holes and all
around the servo mounts.
Use any excess epoxy to seal the ski
(inside and out), as well as one side of
the radio box top. Set these on waxed
paper while they cure.
Use a metal acid brush, bent near the
bristle end to seal the upper part of the
inside of the tub.
Allow to cure overnight.
Sand the top of the tub, so that the
sheeting has a flat surface for gluing.
Glue the aft lid frame in place. This
frame provides the “lips” for the radio
box lid.
This fits in the lower portion of the aft
end of the tub, sitting on the lid frame
support glued to the back of bulkhead 2.
Allow to cure.
Sand the frame, and glue the tub top
sheeting in place with 30 minute epoxy.
Make sure that the sheeting is flush with
the transom and is centered. Look at the
“lip” all around the radio box and make
sure that it is centered as well.
Tape and weight until cured.
