STEP 1
Assemble "r_fs1", "r_fs2" and “r_fs3” using CA glue. You should
place 4 pieces of “pim parts (in asm_parts)” into the centering
holes to facilitate assembly.
Make sure the pieces fit well. If you are using CA accelerator,
you should spray on one side and wait for accelerator to dry for
20 seconds and then you can apply the glue on other side and
assemble the pieces.
Note: Avoid excessive use of glue.

should place 2 pieces of “pim parts (from the asm_parts)” into
the centering holes to facilitate assembly.
Make sure the pieces fitting well on every step.
If you are using CA accelerator, you should spray on one side
and wait to dry accelerator for 20 seconds and then you can
apply the glue onto other side and assemble the pieces same
as fuselage.

STEP 5
Prepare and assemble the pieces of "r_wing2_l" and
"r_wing3_l". Apply the same process for the right wing.
Assemble the pieces of "r_wing1_l", "r_wing1_r" and
“wign support part (from the asm_parts)” together.
Assemble the parts on a flat table surface. So you can be sure
the wing and flaps are sticking in a straight line.
Make sure you use enough CA glue for this step!
Note: Avoid excessive use of glue.

STEP 6
Now you can assemble the right and left wing with the central
part.
Don't worry about the Dihedral Angle, wing support part will
guide the assembly for the necessary wing angle.
Be sure to test fit all the parts before applying the CA glue.
You can stick a piece of tape to the entire leading edge for
extra durability.

STEP 7
1-Insert the carbon pipe all the way into the fuselage and stick it.
2-Insert the wire holder (from the asm_parts) to the pipe.
3-Install the tail wing all the way to the carbon pipe and stick it.
4-Insert the wing mounting bracket (Red part) inside the fuse-
lage where the wing is going to be assembled and then stick it
into the fuselage with CA glue. In this step be careful for the
alignment of the mounting holes.
5-You can stick the m4 nut to the wing mounting bracket with
CA glue carefully before previus step.
6-Now you can assembly the wing to the fuselage with one
M4x25 imbus screw.

7- While sticking the tail wing to the carbon pipe, you can use
the tail mounting stand (from the asm_parts) for the perfect
position of the elevator.
8- Sit the fuselage on a flat table and stick the mounting stand
at a suitable location on the table with double-sided tape. Be
sure the elevator, fuselage bottom and table surface parallel
together.

STEP 8
Remove the wing to work easy on the next steps.
Now you can install all your electronics; install your Motor, ESC,
Lipo Battery, Servos and Ø1 mm Push Rods (Music Wire).
You will need to drill the fuselage from the marked points with
push rod wire from the back of the fuselage for the push rods.
Check your servo direcions on the transmitter. Setup your
EXPO and Level settings.
Flaps should move 6 mm down and 9 mm up on the elevator
and 9 mm equal right and left on the rudder for the first flight.
The 40% EXPO setting is good for easy control on all directions.

Drawings are 1:1 scale in this page. So
you can print this page as %100 scale
and use as a template.
You will need Ø1.5 mm and Ø1.0 mm
music or spring wire.
Be careful in this step and use strong

STEP 11
Prepare the canopy spring using these drawings.
Drawings are 1:1 scale in this page. So you can print this page
as %100 scale and use as a template.
You will need Ø1 mm music or spring wire.
Place the wire you prepared on the inside, approximately as in
the photo, and fix it with CA glue only at the ends. The wire
should be stretching the canopy outward at its ends. This is
going to fit the canopy to the fuselage strongly.

Assemble the wing to the fuselage. Install your canopy and
check if everything is right.
Set the Center of Gravity from the marked line under the wing
(37,5 mm behind from the leading edge).
Take your time and do the right on every step. Be in a ventilat-
ed environment or work outside when using CA glue and ac-
celerator.

Print Guide

You will need a printer which has a bed size at least 180x180x180.
We have optimazed the Ranger Mini for normal PLA but if you
can use the LW-PLA it’s going to be better.
There is settings table on the last page for all of the parts and
we have prepared the necessary .curaprofile files for you. You
will need to use both of them.
First of all you need to have the CURA slicer program. When
you open the program, you can find your own printer from the
list but you should define your own printer with the custom
option. Custom option is always works properly.
Open the Add Printer window, select Custom FFF printer, set
your printer name and click to the add button for the next step

This step, you have to set your printer x, y, z dimensions. If your
printer has a heated bed then you must activate/choose this
setting. (Heated bed is necessary for the wall print.).
Nozzle size has to be 0,4 mm for the model printing process. If
you have a different size nozzle then you have to change it with
a 0,4 mm nozzle. “Compatible material diameter” is related to
your printer, this is the filament daimeter.

The settings you should set according to your printer:
- Material Settings.
Printing Temperature
Buildplate Temperature
Flow (wall flow is important!)
- Travel Settings.
Retraction distance
Retraction speed
These settings are related to your printer and your filament
brand. You should print a test part (any part from the stl files). If
you can print a test part of sufficient quality and the correct
weight, you are ready to print the other parts.
Note: 0,2 mm layer height is the best settings for the
Print Quality/Printing Time. You should follow the table on the
last page.
