Great Planes PT-E Trainer Electric Kit - GPMA0110 - Manual (Page 28)

D D 10. Set the W-l rib in place (do not glue), then lay
the top spar in place.
D D 11. Set W-l at the proper angle, using the die-cut
1/8" ply dihedral gauge. NOTE: The edge of W-l
must line up with the wing centerline(which
should also be the edge of the 1/16" balsa bottom
sheeting).
D D 12. Make sure that the ribs are all down onto the
plan and fully inserted into the notches in the L.E.
and T.E. Also make sure that the spars are seated
snugly down into the notches in the ribs. Check all
parts for correct alignment (especially rib W-l),
then apply thin CA glue to all joints.
D D 13. From the 5-1/2" length of 1/4" balsa triangle,
cut pieces to fit between the ribs in the first two rib
bays. Glue these pieces to the bottom sheeting and
the L.E. as shown on the plan and in the photo.
D D 15. Find the stack of 1/16" balsa shear webs. Cut
one of the webs to fit between the two W-2 ribs and
glue it to the back of the spars. Also glue webs to
the spars in the next three rib bays. (See the detail
drawing showing the webs and braces on the wing
plan).
D D 16. From one of the 1/16" x 1/4" x 18" balsa sticks,
cut diagonal braces and glue these braces to the
spars as shown on the detail drawing.
D D 14. Lay two of the 1/8" x 1/8" x 28" balsa sticks in
the front spar notches, with the ends of the sticks
flush with the outside edge of the tip rib. Make sure
the spars are fully down into the notches, then apply
thin CA to all joints.
D D 17. Sand the leading edge, spars and trailing edge
even with the tip rib, using your T-bar sander.
