Great Planes Ultra Sport 1000 Kit - GPMA0425 - Manual (Page 12)

CAUTION!!!: You must use extreme care when
cutting hinge slots with an X-acto knife, to avoid
cutting yourself! If the balsa part breaks while
you are pushing on the knife, the blade could go
into your hand before you know it! A good pre
caution is to wear leather gloves while performing
this step.
D 2. Cut the hinge slots and temporarily install the
elevator and rudder hinges.

PREPARE WING PARTS
Before assembling the wing, there are several
preliminary assemblies that must be made . ..
D 1. Before using the hard balsa spars, examine
them carefully for possible imperfections Look for
knots, soft spots, diagonal grain and any other
imperfections If possible, position each spar so the
imperfections (if any) are on the outer half of the wing
panel (toward the tip), where they will be least affected
by high stress If the spars are warped slightly, try to
"balance them out" by installing the warped spars in
opposite directions (see sketch) NOTICE: If you feel
that any of the wing parts are unusable due to severe
warps or other defects, give us a call and we'll replace
the parts.
