2 Beaver Instruction Manual
1.
Remove the bulkheads from the 3mm
lite ply sheets. Use a hobby knife to
cut through the joining tabs holding the
parts in the sheets. Also remove Bulk-
head 3 from the 6mm ply sheet.
2.
Glue the Bulkhead 4 Stiffener in place
on the front side of Bulkhead 4, across
the top.
Fuselage
3.
Attach the float mount and strut mount fittings to the aft sides of bulkheads 2, 2.5, 3, and
4 using 4
-
40 blind nuts and 4
-
40 x
3/8”
Socket Head Cap Screws. Bulkhead labels face
forward, so attach the fittings on the side opposite the etched labels, with the blind nuts
on the same side as the labels. NOTE: ONCE THE FUSELAGE IS BUILT, THE FIT-
TINGS ON BULKHEADS 2, 2.5, AND 3 WILL BE UNACCESSIBLE. Use epoxy on the
blind nuts and threadlock on the cap screws.
4.
The blind nuts close to the edge of
bulkheads 2.5 and 3 will probably
overhang the edge of the bulkheads.
Remove the float mounts from these
locations, file the blind nuts flush with
the edge of the bulkheads, and re
-
install the float mounts.
5.
Glue the 2.5mm balsa sheeting help-
ers to the aft side of Bulkhead 4
(labeled
“

and the forward side of
Bulkhead 2 (labeled
“
FWD
”).
6.
If installing a DLE
-
20 engine (not the
-
RA version), trim the forward end of
the floor to the line etched on the top
side, and trim the Motor Box Left Side
to the line etched on it.

side without etching), glue:
a.
The servo mount doublers (nested
in the servo cutouts in the floor,
3mm lite ply)
b.
The landing gear mount (6mm ply)
c.
The servo cover magnet holders
(3mm lite ply, nested in the servo
