Great Planes PT-E Trainer Electric Kit - GPMA0110 - Manual (Page 27)

WING
NOTE The PT-Electnc wing is made to fit together with-
out glue, so you can assemble all of the major parts and
check to make sure they are all lined up before applying
thin CA to the joints
D 1. Turn the plan over to side 2, which shows the
wing Tape the plan to your flat work surface so the
"Right Wing Panel" is facing you Cover the right
wing panel drawing with waxed paper (so you won't
glue the wing to the plan!).
D 2 The shaped and notched wing leading edges
( L E ) and trailing edges ( T E ) are fastened to-
gether by thin layers of balsa Separate them by
folding until the balsa breaks Sand away the excess
balsa that remains along the edges after breaking
them apart, using a T-bar with 100-gnt sandpaper.
NOTE: Save several of the thin little balsa scraps
which will be used in step 8.
D 3 Before using the L E and T E pieces, you must
determine which pieces are to be used for the right
wing panel Here's how
A- We have drawn red lines on the top of each piece
B- Notice that the pieces are notched on one end, but
not on the other The notched end goes toward the
wing tip, and the end without a notch goes toward the
center of the wing.
C- Take one of the L E pieces and lay it on the right
wing panel plan with the red line up If the notched end
is on the right side (at the tip) you have the correct L.E.
D- Do the same thing to determine which T E piece
to use.
D D 4 Pin one of the 3/16" x 3/16" x 28" hardwood spars
to the plan, with the right end of the spar lined up
with the tip (The excess spar length extends past
the wing centerline)
D D 5 Accurately position the three die-cut 1/16" balsa
center section sheets on the plan and pin them in
place Notice the pre-cut openings for the dihedral
braces Edge glue the two rear sheets together with
thin CA, and glue them to the spar.
D D 6. Put the two W-2 ribs and the eight W-3 ribs in
place on the spars (do not glue).
D D 7. Lay the trailing edge in place with the end lined
up with the outside edge of the tip rib on the drawing
(the excess length extends beyond the wing center-
line), and work the ribs into the notches (do not
glue).
D D 8 Lay down some of the 1/32" balsa scraps from step
2 between the ribs at the L E (these will raise the
L.E. 1/32" off the table).
D D 9 Lay the leading edge in place and line up the end
with the outside edge of the tip rib on the drawing
(the excess length extends beyond the wing center-
line) Work the ribs into the notches REMEMBER:
The L E is 1/32" above the table, supported by the
balsa scraps.
