the plans as you’ll have to determine its
size and location from your own engine.
The top forward section of the fuselage
(below the hatch) has four holes for the
cabane-strut wires. You will need to drill
down through the upper longerons to fit
the cabane wires against the inner surface
of the sides. Build the removable hatch
section on top of the fuselage. Tack-glue
the lite-ply base in position, then glue the
top formers to it. Sheet the structure with
balsa and thin plywood, then remove it
and install the retainer magnets. Wood
tabs and screws can also be used to
secure the hatch. Add the fuselage side
formers and stringers, then sheet with
1/8-inch balsa. The sheeting should end
just above the bottom wings, so leave it a
bit oversize and trim to shape using a wing
rib as a guide.
Build each wing panel directly over the
plans. Pin the bottom spars and the trailing
edge ( TE) sheeting in place, then glue the
ribs into place. Glue the top spar into place,
then fit and glue the leading edge (LE)
dowel in place. Glue the half ribs between
the main ribs, then add the aileron subspar
strip and LE pieces, lightly tack-gluing
lite-ply base. This allows the four 4-40
bolts holding the tail to the fuselage to
sit flush with the top surface. Standard
Du-Bro pinned hinges are used
throughout. The vertical fin is held in
place by two 2-56 screws and blind nuts
in the fin’s bottom rib. The rudder’s bottom
hinge uses a removable pin so that the
entire tail assembly can be removed in
Made with four lite-ply sides, the fuselage
has balsa longerons in the corners. The
wing-saddle doublers, vertical members,
firewall supports, and the forward
formers are all glued in place before
joining the sides together. The top and
bottom pieces fit between the sides and
are flush with the upper and lower edges.
Lightly tack-glue the parts together,
using rubber bands to hold the assembly
together. Install the aft formers, check
the alignment, then permanently glue all
the joints. I use Zap CA glue and Z-Poxy
throughout. Glue the top aft formers and
the stringers in place between the cockpit
