Build the Fuselage
Prepare the Fuse Sides
All the parts used during fuselage construction are
die-cut 1/8" plywood unless otherwise specifi ed.
❏
1. Carefully remove the forward and aft fuselage
sides from their die sheets, then remove slivers or
die-cutting irregularities with a bar sander.
❏
2. Lay the forward fuselage sides on your work
bench opposite each other in a “mirror image.”
Mark the inside of the fuselage sides as the “
right
inside ” and the “ left inside ” with a ballpoint pen.
❏
3. Remove the portion of only the right fuselage
side indicated by the perforated line with a hobby
knife and a straightedge.
❏
4. Glue the aft fuselage sides to the forward
fuselage sides with medium CA. Work over the plan
covered with wax paper to make sure the pieces
align. Use a bar sander and 150-grit sandpaper to
sand the two sides so they are fl at and even.
❏
5. Glue a servo rail support to the inside of both
fuselage sides at the location shown in the photo.
❏
6. Place one of the fuselage sides on a piece of
scrap wood, then drill a 3/16" hole at both punch
marks for the wing dowels. Press down on the
fuselage side to keep the drill from splitting the
wood as it goes through. Repeat for the other
fuselage side.
❏
7. While you have your drill and bits out, drill an
11/64" hole at the forward landing gear wire punch
mark in the right fuse side and the aft punch mark
in the left fuselage side. If you do not have an 11/64"
drill, you may use a 5/32" drill but you will have to
enlarge the hole slightly with a hobby knife.
❏
8. Use thin CA to glue the 1/4" x 36" balsa triangle
fuselage reinforcement stringers to the top and
bottom of the inside of both fuselage sides. Be
certain you glue the stringers to the inside
of the fuselage sides.
The front of the stringers
should be 1/8" aft of the front edge of the fuselage
sides (for F-5). Make the “splice” in the stringers
as shown on the plan at the rear of the fuselage.
