CUT HINGE SLOT

WITH HOBBY KNIFE
AND No. 11 BLADE

After the first shallow cuts, make several more cuts
going slightly deeper each time. Move the knife from

side to side and widen the slot as you cut.

Q 6. Carefully separate the elevator from the stab.

Then use a ballpoint pen and a straightedge to

lightly draw a line 1/16" from the leading edge on

both sides of the elevator.

7/16"

Q 7. Use the lines as a guide to bevel the leading
edge of the elevator to a "V" with a hobby knife or a
bar sander and 220-grit sandpaper.

3/4"

MAKE SIX 7/16" X 3/4" HINGES FROM

THE 2" X 9" HINGE STRIP PROVIDED

Q 4. Cut six hinges from the hinge material
supplied as shown in the sketch. Snip the corners off
so the hinges go into the slots easier.

LJ 8. Bevel the leading edge of the rudder the same

way you did the stab.

Q 9. Use your bar sander and 220-grit sandpaper

to round the perimeter of the tail surfaces as shown
on the plan (except of course, the edges that are

joined by hinges).

There, that was a "piece o' cake," wasn't it? Set the
tail surfaces aside for now while you build the wing
and the fuselage.

U 5. Test join the elevator to the stab, and the
rudder to the fin with the hinges. Adjust the hinge
slots if necessary so the control surfaces fit well.
