1. Former Sub-Assembly
F1 Servo Tray F2
A. Assemble F1, Servo Tray, and F2 with adhesive.
B. Proceed immediately to step 2.

2. Fuselage Former Installation
F3
RH Fuselage Side
A. Pre-bend fuselage sides at F2 position.
B. Insert F1/Servo Tray/F2 assembly with adhesive.
C. Dry fit F3 and do not glue until LH fuselage side is installed in step 4-B.

3. Monoblock Sub-Assembly
A. Monoblock is shown with rounded
front and beveled bottom. This
should be done after the fuselage
is assembled.
B. Assemble a left and right sub
assembly with filler blocks. Allow
the adhesive to dry so that the
outside can be sanded flush to
mate to the fuselage sides.
C. Filler blocks are designed at .50”
thick, but that can be adjusted to
suit your battery preferences.
D. Then assemble left and right sub
assemblies into one block. View

cavity

4. Monoblock and LH Fuselage Side Installation
A. Apply glue to
monoblock
sub-assembly
and add to RH
fuselage side
assembly.
B. Glue and
install the LH
fuselage side,
and glue F3 to
both sides.

5. Install Lower Fuselage Panel
C. New design on bottom panel is
tabbed to fuselage to help
maintain alignment during
assembly. Not shown here.
B. Bevel all
mating surfaces
to insure a water
tight strong glue
joint.
A. Groove the inside centerline of bottom panel to allow easy folding. Then add
glue to centerline joint to strengthen. Now add fuselage bottom panel.

6. Fuselage Top Panel and Wing Rubber Band Dowels
You may omit
gluing the wing
dowels at this time
until after any color
trimming is
complete.
C. Install wing
rubber band
dowels.
This completes the
basic fuselage.
A. Add fuselage
top panel.
B. Shape nose
and hull of the
monoblock.

7. Horizontal Stabilizer/Elevator Assembly
A. Add brace to elevator. I used a pine stick
that was scrap from ripping wood on the
table saw. Just under 1/8” sq. X 6” long
B. Use your favorite method to hinge
elevator to the horizontal stabilizer.
C. Place a strip of 2” packing tape folded
over the leading edge, being careful not to
have any tape where the stab will glue to
the fuselage.
D. Packing tape adds spanwise strength.

8. Vertical Stabilizer/Rudder Assembly
Hinge rudder to
vertical stabilizer
and attach optional
water rudder and
compression
washer with a 2-56
machine screw and
nut.

9. Stabilizer to Fuselage Installation
A. Please note that the latest
parts have tabbed
components to aid alignment.
B. After adding horizontal and
vertical stabilizer assemblies,
check for square and true to
centerline of fuselage.
