Q 4. Remove the engine (so it does not get balsa
dust in it), then sand the cowl blocks so they are flush
with the fuselage. Round the front edges of the cowl
blocks for a finished appearance. Start with your
bar sander and 80-grit sandpaper, then finish by
hand-sanding with 320-grit sandpaper. Reinstall
your engine just to see how it looks!

Q 5. Drill 3/16" holes in the fuselage sides at the
locations shown in the sketch for the wing dowels.
Cut the 6-1/2" dowel in half. Use sandpaper to
chamfer the ends of the wing dowels, then test fit
them in the fuselage, but do not glue the dowels in
place until instructed to do so. U 2. Accurately mark the center of the fuselage top
sheeting at the front over F3 and at the rear. Position
a straightedge on the fuse top and align it with the
centerlines you marked. Then place the stab on the
fuselage and align the centerline of the stab with the
straightedge. Temporarily attach the stab to the
fuselage with T-pins.
Q 1. Remove the elevator from the stab, then mark
the center of the stab. Use a builder's triangle to
mark a centerline on the top of the stab at the mark.
U 3. Carefully turn the fuselage over and lightly
mark the outline of the fuselage sides on the bottom
of the stab. This line indicates where to apply the
covering "up to" and apply glue when it is time to
glue the stab to the fuse.
