-Instruction manual-

1-) Locate the stab/elevator
assembly. From the bottom Left
side, cut into the covering,
exposing both pre-cut slots.
2-) Using a sanding bar, sand
the top section of two supplied
control horns on both sides and
clean with alcohol.
3-) Sand one side only of the
horn retainer as shown. The
sanded side will face on the
elevator surface.
4-) Trial fit both horns with the
horn retainer and adjust as
required for perfect matting.

5-) Insert the horn assembly into
the Left elevator and cut the
covering around the horn
retainer.
8-) Align both horns so that the
holes in both of them are
parallel to each other. Let the
epoxy cure. Repeat the same
process for the Right elevator.
7-) Also apply epoxy on the
horn assembly, where it will fit
into the elevator.
6-) Remove the covering. Mix
some 30-minute epoxy and
apply some into the elevator
slots.

9-) Locate the rudder and
repeat the same process as the
elevator to open the cavity for
the rudder horn.
12-) Slide one retainer as
shown to keep the assembly in
line. The sanded surface must
face inwards of both horns.
11-) Also sand the two rudder
horn retainers (Left/Right) and
clean with alcohol.
10-) Sand the two rudder horns
(center-section only) and clean
with alcohol.

13-) Like the elevator, apply
epoxy to the horn assembly
and insert into position.
16-) Locate the wheel &
accessories.
15-) Repeat the horn assembly
proceedure for both ailerons.
14-) Position the second horn
retainer with epoxy and adjust
both horns so that they
properly match.

17-) Insert the screw from one
side, slide on one spacer and
the wheel.
20-) Do the same on the front of
the stab fuselage saddle section
to expose the pre-installed blind-
nuts.
19-) On the top and bottom (front
section) of the stab, locate the
two small holes. Remove the
covering to expose the holes.
18-) on the other side, slide the
other spacer, push in the screw
and secure the screw using the
Nylon lock-nut.

21-) Underneath the stab, at
the rear section, notice the
small notch.
24-) Position the rudder onto the
fin by aligning the pre-installed
hinges and slide the steel wire
through all of the hinges as
shown.
23-) Position the stab by sliding
it into the inter-lock inside the
fuselage and secure it with two
40mm screws and washers. Once
positioned, glue the stab to the
fuselage, after final assembly
only.
22-) This notch will inter-lock
with the fuselage stab saddle
section.

25-) Push the steel wire until it
reaches the bottom hinge as
shown.
28-) On the rear Left side of the
fuselage, in front of the stab
saddle, open the elevator servo
cavity by cutting the covering
film.
27-) Then, cut the steel wire
flush with the wheel collar.
26-) From the top, slide the
plastic round disc and secure it
with the small wheel collar.

29-) The elevator servo requires a
48’’ (121cm) servo lead extension.
Secure both the servo and the
extension with one of the supplied
Grey safety clips.
32-) Insert the elevator servo.
Drill small pilot holes and
secure with servo screws.
NOTE: The front of the servo
must go towards the front of
the fuselage.
31-) Cut off the string and
attach it to the servo extension
lead. Use tape to “wrap”the
string around the connector.
Inside the cockpit section, pull
on the other end of the Red
string and pull in the extension
lead.
30-) Inside the fuselage, there
is a small wood piece with a
Red string attached to it. Snap
off the wood piece.

33-) Secure the stab to the
fuselage. Plug your elevator
servo in your receiver and
center it. Attach the supplied
elevator pushrod to the servo
arm. That pushrod as two ball-
links factory installed onto it.
36-) Carefully seek the small
cavity for the rudder pull-pull
cables on both sides of the
fuselage. Look at the picture
carefully for reference. Use a
knife to cut and remove the
covering.
35-) Completed elevator
assembly. Now, remove the
stab for the next step. Repeat
the process for the Right
elevator servo.
34-) Attach the other end of
the pushrods to the elevator
horn. Use the supplied key to
adjust the pushrod
mechanically.
