Step 1
Dry fit the Horizontal stabilizer to the
fuselage and trim/adjust if necessary to get
a good fit.
Step 2
Apply foam safe glue to the top and bottom
of the fuselage opening as per the photo.
Step 3
Slide the horizontal stabilizer in place, make
sure it is square to the fin and fuselage and
allow to dry.
Step 4
Dry fit the rudder to the fin and trim/ adjust
if necessary to get a good fit. Make holes in
rudder for pin hinges.
Step 5
Apply a little petroleum jelly to just the
centre of the pin hinges (to stop the glue
from seizing them up)
Apply foam safe glue to three slots and pin
hinges on the tail of fuselage.
Step 6
Glue the 3 pin hinges in the rudder first,
ensuring the are at the correct angle
Apply glue to the three rudder connectors
and pin hinges, DO NOT apply glue to the
tail wheel wire. Insert into the pre-cut
slot/holes in the rudder. Make sure the tail
wheel wire is also inserted in the rudder
when gluing the rudder on. Ensure no glue is
on the centre part of the pin hinges
Step 7
Secure two servos on the servo plate in the
fuselage using the servo screws supplied
with the servos as per the photo. The holes
are cut for the Emax ES3001 servo. To get
at the rear screws, cut the piece of foam out
at the bottom of the slot for the canopy.
Step 8
Connect the servos to the push rods using
the swing keepers.
Step 9
Secure the white control horn and backing
plate on the elevator with two M2.5 by
16mm long self-tapping screws.
Connect control wire to the servo control
horn on the elevator. Clip the Swing Keeper
in place to stop the wire coming out of the
control horn as per the photo.
Step 10
Repeat for the rudder.
Step 11
Attach the motor to the “X” mount
(supplied)
Step 12
Install the motor assembly on the motor box
using the 10mm spacers (supplied).
Step 13
Install the Prop driver on the motor using
the 4 screws supplied with the motor.
Step 14
Remove any pre-soldered ends of wire and
solder (only using leaded solder) your
connector of choice to the battery side of the
ESC, paying close attention to the polarity.
You will most probably need to extend the
battery wires from the ESC.
Step 15
Attach the ESC to the side or bottom of the
wooden motor mount as per the photo and
connect the 3 wires to the motor.
Step 16
Secure the cowling to the fuselage with four
M2.5 by 25mm long self-tapping screws.
Step 17
Install the wheels on the landing gear wire.
Lock the wheel in place with the supplied
wheel collets.
The wheels should rotate freely, but not be
loose, adjust if necessary.
Step 18
Install the spats to the undercarriage leg
using the two M2.5 by 10mm long screws as
per the photo.
.
Step 19
Trim the landing gear covers to fit with a
sharp knife and secure landing gear foam
covers on the landing gear assembly with
foam safe glue.
Please note that they are handed.
Step 20
Insert the landing gear into the slot on the
bottom of fuselage. Then Insert the landing
gear plate into the slot.
Step 21
Secure the landing gear plate using two
M2.5 by 10mm long self-tapping screws.
Might be a good idea to add a washer (not
supplied)
Step 22
Secure the white control horn and backing
plate on the aileron using two M2.5 by
16mm long self-tapping screws. Ensure the
servo is centred before gluing it in place
using foam safe glue. Connect swing keeper
to the servo. Clip the clevis to the control
horn on the aileron as per the photo.
Attach the servo extension lead to the servo
and either glue or tape in place so they are
flush to the bottom surface of the wing.
Step 23
Install the small fuselage wing (canalyzer) to
the top of the fuselage just behind the
canopy using foam safe glue ensure it is fully
seated and square to the fin and parallel to
the horizontal stabilizer.
Step 23
Install the right and left wing on the fuselage
using the carbon fibre tube supplied. Feed
the servo leads through as per the photo.
Step 24
Insert the two wooden wing locking plates
in to the pre-cut slot in the fuselage.
These lock the wings in place.
Tip: Add a bit of tape to one end of the ply
plates to allow you to remove them once
installed.
Step 25
Install the propeller and cooling Spinner to
the motor. Make sure the propeller spins
freely and doesn’t touch the plastic nose
cone
Step 26
Install your receiver and check all surfaces move in the correct direction.
As you have purchased this model we assume you’re are a competent flyer and are familiar
with this.

The CG should be 135mm from the leading edge of the wing.
