Assembly

STEP 1
Glue the "lipo_mount" part to "fs2", then glue the
"fs1-nose-fs2-fs3" parts together using CA glue. You can insert
the “cub_pim” parts (Ø3x12 mm) into the guiding holes for
each parts to facilitate assembly.
Never spray the accelerator directly onto the CA glue! Spray on
first piece and wait for 15 seconds to dry it. Then you can aply
glue on the other piece and put the pieces together.
Note: Avoid excessive use of glue.

STEP 2
Glue the "fs4" - “elevator_r” - “elevator_l” parts together. Take a
little piece of 2 mm steel wire and bend with the dimensions
(as milimeter) as below and glue into its slot under the
elevator. This wire will distribute all the force to both sides.
2 mm steel wire will also be required to make landing gear too.

STEP 3
Release the elevator flaps from the elevator by breaking it’s
tiny connections.
Reassemble and glue the flaps using TPU hinges or CA hinges
that you prepared by using Hinge Maker Tool (Free on
craycle.com).
Note: The CA accelerator sprayed to stick the elevator may
have contaminated the hinge slots! Take your time, apply the
glue onto the hinges one by one and insert into the slots on
the flap first.

STEP 4
Glue the "rudder1" and “rudder2” parts together by inserting
“cub_pim”.
Glue the rudder you prepared to the tail by inserting hinges
into it’s slots.
Note: The CA accelerator sprayed to stick the elevator may
have contaminated the hinge slots! Take your time, apply the
glue onto the hinges one by one and insert into the slots on
the rudder first.

STEP 5
Clean the little “rearbracket” parts and glue onto the slots on
the rudder. Assemble the “wheel14_rim” and “wheel14_ring”
parts together to get rear wheel.
Assemble the rear wheel to the rudder by using a 2 mm servo
mounting screw or something similar.
That's it! You have a rear landing gear with the steering system.

STEP 6
Take the servo as position as the same with the image above
and scew onto the “wing1” part. Also, you need to trim the
servo arm using cutting pliers as in the image above. Then you
can glue the “wing1”- “wing2” and “wing3” parts together by
inserting pims into the its slots. Be careful not to apply glue to
the servo and same process goes for the other side.

STEP 7
Insert the “wingspart” to the fuselage and glue it from the
inside of the fuselage (Make sure it is centered with the
reference lines on the wingspar).
Insert the servo cables to the fuselage. Assemble the wings to
the fuselage and glue them together. Hold the wings as
horizontal as possible during the gluing process. Wing
supports will align the wings as well.
Stick the tail that you prepared to the fuselage by inserting it’s
pim to facilate assembly.

STEP 8
In this step, take your time and do it right!
You need to be sure the wings are holded in a straight line
(Hold the model upside down on the flat table).
Then you can screw the “wingsupport” part by using 2 mm
screws (Servo mounting screws) into the holes on the wings
and fuselage.
When assembly is complete, turn the model over and check
the flatness of the wings.

STEP 9
Install your servos to the fuselage and prepare 2 pieces of 1,2
mm pushrods which is approximately 210 mm length.
You can make Z bend for the both side or use rod linkage to
make detachtable and facilate to set the flap positions.
For this model, the best way to mount the push rods is; Z-bend
is mounted on the outside, the push rod connectors are
mounted on the servo arms inside. In this way, connectors are
installed quick, it becomes possible to deassemble the wires,
and the objects that will create drag are reduced on the
outside.
You can use cheap 9 gram servos for this model becouse of it's
not required high sensitive on the control surfaces.

STEP 10
Prepare quick release landing
gear by using 2mm steel wire. You
can use this page by printing as
%100 scale and also you can use
the dimensions as mm.
Assemble the “wheel35_ring” and
“wheel35_rim” parts together and
install them onto the landing gear
that you prepared (You can make
a clear hole in the “wheel35_rim”
by drilling it with 2 mm drill bit.)
Glue the “spinner_adaptor” and
“spinner_base” parts together by
inserting 5 mm rod to make it
centered. Assemble the spinner,
motor and landing gear as shown.

STEP 11
Now you can install all your electronics. Make transmitter
settings (Use 40% Expo and set 11mm up 9mm down control
movement for ailerons and elevators for the maiden. Set 11mm
right and left for rudder ).
Glue the “lock_body” part into the “hatch1”. Assemble the
“lock_catch” part by using m3x8mm bolt (Comes with
brushless motors). Insert and stick the “cub_pim” parts
corresponding to the hatches into the fuselage (Red pims in
front of the wingspar.) Assemble the “hatch2” to the fuselage
by using 2 mm screws.

Epilogue

Center of Gravity is 29,5 mm behind from the leading edge
(There is a marked point under the wing).
You can add extra weights into the “fs1” to make CG correct.
You can also print FS3 and all tail parts with LW-PLA to make
the rear lighter. You can also print this model completely LW
but it’s not necessary at all. We are developing all of our
models by using Regular PLA to provide accessibility.
We recommend 6” propellers for this model but if you want to
make a trainer model, the bigger propellers will make the
model slower in the air. So you can use 7” propellers to make a
park flyer.

We have prepared printer profile on Cura Slicer for you. If you
have a Marlin XYZ type printer, you can print directly with
prepared gcodes as well. If you can’t use the gcodes don't
worry, just follow the instructions...
Download and install CURA Slicer on ultimaker.com.
When you open the program, you can find your own printer
from the printer list but if you are getting error on importing
curaprofile, you will need to create Custom Printer to import a
curaprofile succesfully.
