COMMENTS

This model does not have float mounts in it. The model would need to
be modified to accept floats. The GPMQ1874 60-size Float Kit will
work with this kit.

If a replacement fuel tank is needed, an 8oz (240cc) tank such as the
SULQ1439 can be used. Some minor modification may be needed as this
is not the exact shape of the original tank.

About joining wings- pg.6 of instructions says to test fit the wing
halves and to sand any high spots on the root end of the wings so
there is no gap when you join them. If there is too large a gap to
sand away, it may be shimmed with a piece of balsa and balsa filler
or epoxy. The idea is that the wing is straight upon assembly,
and has no twisting motion at the joint. Epoxy gives more weight
than balsa filler, or micro balloon filler which can also be used
to fill the gap. This wing is flat-bottom and can be assembled on a
flat surface. The landing gear wires are taped to the underside of
wing support cardboard.
