CFD Analysis
USER MANUAL 4
Geometry is designed to provide the best possible characteristics. Excellent
and well-tested PW75 airfoil was selected for this project. It is a reflex airfoil
designed specifically for planks. With the center of gravity located 35mm from
the leading edge, stability and the zero pitching moment at zero angle of attack
is maintained. Angles of attack for optimal CL/CD distribution are in the range
of 2 to 4 degrees. The optimal cruising speed is between 45 and 55 km/h.

Print Settings
USER MANUAL 6
Slicer software you need to use is Ultimater Cura. All elements from LW-PLA
are best printed with ready-made settings prepared in a profile that you can
download. Settings are prepared a standard 0.4mm nozzle. Download link is
available on Flightory Blog. Infill in this profile is set to 6%. For this project I
recommend changing it to 3%. This is sufficient filling
Main features of slicer LW-PLA profile
•layer height: 0,25 mm
•single wall 0,4mm thickness
•3% Gyroid infill.
•Temperature: 235 degrees,
•flow 60%
•fan speed: 0%
The rest of the detailed settings are
saved in the profile.
To print hard PLA or PET-G parts, use
a default profile in CURA called
Draft. Layer height is 0.2 mm, infill
is 20% Grid pattern. Set the
temperature around 220 degrees.
You can fine-tune these parameters
to suit your needs and your printer.

Parts Orientation
USER MANUAL 7
All parts are suitable for printing on any standard printer with a small
working area. I printed all parts on a 200 x 200mm area. The settings
are just a base that you can change and adjust as needed. The
following pages will list my recommended infill settings for each part.
All elements can be printed without supports, but your printer
may have a problem with some horizontal surfaces in some
places. Depending on the effects, you may then consider turning
on supports for some elements and cleaning the printed
elements afterwards.

Parts Orientation
USER MANUAL 8
Important thing is the correct orientation of the printed parts
to avoid overhangs, and not have to use supports.
Below is the recommended orientation of parts and infill settings.
FUS 1 - 3% gyroid infill
FUS 2 - 3% gyroid infill

STEP files
USER MANUAL 16
A few airframe parts are also available in STEP format. This way you
will be able to customize these items. For example, make a mount for a
custom camera, a mount for a VTX, GPS or change the size of the
servos used.
You can find these files in folders labeled STEP

Nose variants
USER MANUAL 17
There are 2 variants of the nose in the files. One of them is adapted for
a standard 19x19mm FPV camera. A clean version is relevant if you
don't want to mount an FPV camera. The nose file is also available in
STEP format for easier editing and customization.

Fuselage assembly
USER MANUAL 19
Prepare all fuselage segments. Before gluing,
you can gently sand the surface of all
elements, especially the gluing surfaces.
It’s best to use thick CA glue.
You can use short pieces of 4mm carbon tube as pins
to strengthen the connection. This is an optional action

Fuselage assembly
USER MANUAL 20
It’s best to use thick CA glue.
After gluing all the fuselage segments together, attach the ROOT parts.
