1. After unpacking all parts, sort the
hardware and place like parts into
separate holders. This will speed the
building process and give you a good
visual of all the hardware provided.
2. Begin by hinging the ailerons to the main
wing panels using the CA hinges. Insert
the hinges fully then flex and apply thin
CA glue to the hinges from the top and
bottom allowing the glue to wick into the
wood.
3. Once the hinges are set, flex the ailerons
a few times to break-in the hinge.
4.
Now install the flaps in the same manner
as you did the ailerons. Use 5-minute
epoxy to glue the metal control arm into
the slot of the flap.
5.
After all wing control surfaces are
hinged, check for free movement and
prepare to install the servos.
6.
Pull the aileron servo covers out of the
wing. Trail fit your servo and drill small
pilot holes where the servo screws will
go. Add 12” servo extensions to the
servos and install them into the cover as
shown using the hardware provided with
your servos.
3

7.
Slide the servo wires through the wing
and install the hatch using 4 of the
smallest wood screws per hatch.
8.
Install the nylon control horns to the
ailerons. The nylon control horn positions
are marked on the surfaces with pre-
drilled pilot holes.
9.
Install the aileron pushrods to the servo
arm and the control horn as shown.
10.
Place the flap servo in the wing as
shown. Place the aluminum servo cover
over the servo and screw in place using 4
of the smallest wood screws.
4

11.
Find the two plastic arms and screw them
onto the threaded flap control rod. You
may have to drill out the plastic arm for
an easier fit. Next, install the “Y” shaped
pushrod linkage onto the servo and
connect to the flap control arm as shown.
You will connect the other side when
joining the wings.
12.
Slide the aluminum wing joiner tube into
the wings and slide together. You can
connect the flap linkage at this time.
13.
Locate the two main landing gear wire
pieces, two wheels, 4 aluminum plates, 4
wheel collars, and 8 wood screws.
14.
Begin by inserting the wire gear into the
wing slots. Use the aluminum plates and
wood screws to secure the wire to the
wing.
5

15.
Install the wheels using a wheel collar
on both sides of the wheels.
16.
Locate the plastic nose gear mount, and
the plastic pushrod with the wire in it.
Install the pushrod through the slot shown
making sure the side with the Z-Bend is
facing forward. Install the plastic nose
gear mount using 4 wood screws.
17.
Find the plastic nose gear control arm
and connect it with the Z-Bend on the
pushrod.
18.
Slide the nose gear through the mount
and control arm. Use the provided screw
to secure the nose gear to the control
arm. Note: When the nose gear is
pointing straight ahead, the steering arm
will be at an angle as shown.
6

19.
Install the nose wheel as you did with the
main wheels using a wheel collar on both
sides of the wheel.
20.
For the next steps we will first need to
install the wing. Place the wing onto the
fuselage and use the large nylon wing
bolts to secure the wing to the fuselage.
21.
Install the elevator to the horizontal
stabilizer using 6 CA hinges.
22.
Mark the centerline on the bottom of the
stabilizer.
7

23.
Place the stabilizer onto the fuselage and
make the area where it touches the
fuselage. Your stabilizer should look like
the photo now.
24.
Find the 2 balsa triangle pieces and lay
them down on the outside of the lines you
just marked with the back edge of the
pieces at the hinge line as shown. Trace
around the pieces.
25.Your stabilizer should look like the photo.
Use a soldering iron and run the iron
along the outside lines, but place the iron
just inside those lines.
26.The iron will melt the covering cleanly
without damaging the wood and you can
peel the coving away from the middle.
8

27.
Apply 30-minute epoxy to the fuselage
area where the stabilizer will mount.
Place the stabilizer onto the fuselage and
make sure it is centered. Wipe up any
access glue with a paper towel and
rubbing alcohol.
28.
Sight down the fuselage and make sure
the horizontal stabilizer is parallel to the
wing. Once the epoxy glue has fully
cured, you can remove the wing for
easier assembly of the next steps.
29.
Place the vertical stabilizer into the slot of
the horizontal stabilizer. Check for a good
fit and straightness. Use epoxy or thin
CA glue to secure the vertical stabilizer.
30.
Install the rudder using CA hinges and
thin CA glue.
9

31.Install the rudder and elevator nylon
control horns as shown.
32.
Glue the balsa triangle pieces in place
using epoxy or thin CA glue.
33.
Find the two long carbon fiber pushrods.
Inset them into the holes at the back of
the fuselage, one on each side. The end
with the Z-Bend goes in first.
34.Make sure the pushrods go into the
correct holes inside the fuselage.
10

35.
Install the rudder and elevator servos in
the fuselage with the output arms facing
the rear as shown.
36.
The rudder servo will need a double-
sided control arm as shown. Install the
included EZ-Connector onto one side.
37.
Center your servos and install the control
arms and linkages as shown. Center the
nose wheel before tightening the EZ-
Connector to its pushrod.
38.
Adjust the clevises at the tail and install
onto the rudder and elevator making sure
the surface is in the neutral position.
11

39.
The receiver can be mounted using
Velcro or double-sided tape. You can use
6” extensions for the aileron and flap
channels to make it easier to install the
wing.
40.
The motor mount and fuselage firewall
both have centering marks on them. Hold
the mount up to the fuselage and align
the marks to center the motor mount.
Mark the positions of the 4 outer holes
onto the firewall. Remove the mount and
drill a 1/16” pilot hole through the firewall
at the marked positions.
41.
Install the radial mount plate onto your
motor. This kit does not provide hardware
to mount the motor to the motor mount.
Use 4 allen head screws and lock-nuts to
secure the motor to the motor mount as
shown.
42.
Use 4 wood screws to attach the motor
mount to the firewall.
12

43.
Connect your ESC to the motor and
install on the side of the motor mount with
Velcro. Use zip ties to secure the motor
wires so they will not interfere with the
motors operation. The power leads for the
ESC should be placed inside the hole
shown for access to the battery.
44.
With the fuselage upside down, trial fit the
cowling and mark where the nose gear
wire touches the cowling.
45.
Use a knife or a dremel tool to cut out a
slot in the cowling that is 7/8” long and
1/4” wide.
46.
The cowling should be able to slide on
the fuselage fully without interference
from the nose gear wire. Trim the cowl as
required.
13

47.
Use a 1/16” drill bit to make a pilot hole
through the cowling and fuselage to
create 4 mounting points, two on each
side.
48.
Use 4 of the smallest wood screws to
secure the cowling.
49.
Install your prop, washer and nut.
50.
Install the battery through the front hatch
and use the included Velcro straps to
secure it. Adjust the batteries position to
achieve the proper center of gravity,
which is shown below.
14

51.Install the magnetic hatch by putting the
back end in first and then laying the front
down. Remove the hatch by first lifting
the front and pulling up and away.
52.
Congratulations, you’ve finished the
assembly. Follow the information listed
below for recommended control throws
and center of gravity.
