WING ASSEMBLY.
NOTE: We highly recommend using 30
minute epoxy as it is stronger and provides
more working time, allowing the builder to
properlyaligntheparts.Usingfastcureepoxy

 1)TestfittheWingtubeintoeachwinghalf.
The brace should slide in easily up to the
centreline that you drew. If not, use 220 grit
sandpaper with a sanding block and sand
down the edges and ends of the brace until it
fits properly.
NOTE:To avoid scratching your new aero-
plane we suggest that you cover
your workbench with an old towel.
