WARPED WING
D 1 Before using the basswood 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 (towards the tip)
where they will be less 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.
D 1 Carefully punch out all the die-cut balsa wing ribs
Sand the edges slightly to remove any die cutting
irregularities and arrange them into stacks of the same
kind of ribs.
D D 2 Locate the two #3 and #4 ribs Center one #3
rib on one #4 rib using the lightening holes as a
reference There will be a 3/32" offset between the
edges of rib #3 and #4 when properly aligned
NOTE: The embossed "T" on both ribs should face the
same direction While holding in the above position, glue
these two pieces together with thin CA NOTE: The ribs
are not symmetrical, so be sure to make a right and left
assembly
D 3 Locate the two 1A rib sections Take care to align
these ribs using the notches as references Glue the 1A
