USER MANUAL 3
General Aircraft Data
The aircraft features a swept wing design with a single pusher motor located at
the rear. It is crafted with compactness and modularity in mind. Geometry has
been carefully designed and optimized using CFD and real test flights. The
wings, as well as the nose of the aircraft, are detachable. This allows it to be
adapted to carry various payloads such as different types of cameras and
sensors. By default, it is prepared for a standard 19x19mm FPV camera and any
VTX. All files are available in STL format, and some are also available in STEP,
allowing for easy editing and adaptation to different cameras, sensors, etc. The
recommended equipment ensures high performance and stable flight even
below half throttle. The maximum recommended battery is a 4S4P 14Ah,
which allows for nearly 3 hours of flight time. The choice of motors and battery
capacity depends on the user and is crucial in determining the aircraft's
performance for specific purposes.
USER MANUAL 4
CFD Analysis
The geometry has been designed and optimized to achieve maximum efficiency while maintaining the
stability of the aircraft. The airfoil used is Selig S5020. With the correct center of gravity set at a distance
of 60mm from the leading edge (measured at the wing root), the aircraft maintains a longitudinal stability
margin and zero pitching moment at zero angle of attack. The highest aerodynamic efficiency occurs
between 2 and 4 degrees of AoA at a cruising speed between 60-90 km/h. With the recommended motor
and propeller and 4S battery, the aircraft flies steadily in level flight at approximately 40% power, resulting
in an average current draw of 5A and providing nearly 3 hours of flight time. There is considerable
flexibility in the choice of motor and battery, depending on user preferences.

Print Settings
The recommended slicer to use is Ultimaker Cura. All LW-PLA parts, print
using the recommended settings detailed on the Flightory website under
the Print Settings tab. Whether you are using prefoamed or active foaming
LW-PLA, you will find settings for both of these filaments there.
For printing parts with hard materials such as PET-G, ABS, or PLA, use the
default CURA profile called DRAFT with 20% infill and a cubic pattern.
Feel free to modify the settings according to your needs, but the
recommended settings provide a good compromise between weight
and the strength of the printed parts.
USER MANUAL 12
Print Settings
All parts are suitable for printing on any standard printer with a small
working area. I printed all parts on a 220 x 220mm 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.
Important: In the file package, you will find fuselage segments divided
into left and right sides, as well as assembled into a single piece. For
printers with the mentioned print area of 220x220mm, use the
components divided into left and right sides. If you have a larger
printer, you can print the fuselage segments as a whole if they fit.
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 these elements and cleaning the printed elements afterwards.
USER MANUAL 13
Parts Orientation
Important thing is the correct orientation of the printed parts
to avoid overhangs, and not have to use supports.

USER MANUAL 23
NOSE VARIANTS
There are 2 variants of the nose. You can choose version with a VTX
mounted inside and a 19x19mm FPV camera, or a clean version
without any mounts. The VTX mounts on a "shelf" and the available
space is sufficient to accommodate any VTX.
The nose is fully removable, mounted on four M3 screws. It is also
available in STEP format for easy editing. You can edit this part and
adapt it to your own more individual needs and to mount different
payload. You can also have several versions of the nose and change
them according to the needs of a particular mission.
USER MANUAL 24
MOTOR MOUNTS
There are two types of motor mounts available, differing in screw
spacing. One has a fixed spacing of 19mm, while the other has two
screws spaced at 19mm and other two at 16mm. These are the most
common dimensions for motors of this class and size. If your motor
comes with a metal mount plate, you can omit it and attach the motor
directly to the printed motor mount. This part is also available in STEP
format, so if any changes are needed, you can easily make them.
USER MANUAL 25
STEP FILES
All files are available in STL format. In addition, some important
elements are available in STEP format, which allows easier editing
and customization.
You can find these files in folders labeled STEP
USER MANUAL 26
Fuselage Assembly
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.
If you printed the fuselage segments
divided to left and right side, simply
glue them together also.
USER MANUAL 27
Fuselage Assembly
Prepare parts printed with PET-G or other hard
material. Take the BATTERY PAD and paste
it in the designated place in the front of the fuselage.
Take FUS ROOT and glue with CA to the
fuselage in the corresponding places.
It’s best to use thick CA glue.
USER MANUAL 28
Fuselage Assembly
Now take M3 threaded inserts with an outer diameter of 5mm.
Glue them into the designated places in the front part of the fuselage.
You can use a slightly heated soldering iron for this. Then glue NOSE
REINFORCEMENT printed with PETG or other hard material. This noticeably
increases the strength of the nose when it is frequently unscrewed and
prevents the threaded inserts from being torn out.
It’s best to use thick CA glue.
USER MANUAL 29
Hatches
Take the hatches parts and assemble them. Insert LOCK 1 and LOCK 2.
Assemble it, adding a small spring, and glue it in the designated place.
Use a small amount of CA glue, but be careful not to spill the glue and
block the lock.
USER MANUAL 30
Nose Mount
Now you can mount the nose with short M3 screws. If you are
using version with VTX, you can put your VTX on the "shelf"
and cover it with NOSE VTX COVER and secure the antenna.
USER MANUAL 31
Motor Mount
Choose the motor mount that matches your motor and attach it.
In the rear part of the fuselage, there are places for M3 threaded
inserts on both the top and bottom. Insert the threaded inserts
into these spots. Mount the prepared motor in the fuselage,
securing it with M3 screws. The motor cables should run through
the bottom and enter the fuselage through the designated
opening.
USER MANUAL 32
Fuselage Assembly
The fuselage is ready, now it's time to assemble the wings.
USER MANUAL 33
Wings Assembly
Glue the wing segments together. Insert a 6mm carbon tube cut to a length
of 350mm. There is no need to glue the tube, just insert it into the designed
slot
USER MANUAL 34
Wings Assembly
Finally, install the WING ROOT printed from PETG or another rigid
material. In the lower part, there are designed slots for regular M3
nuts, which will be responsible for attaching the wings to the fuselage.
Insert them there and secure using a few drops of CA glue.
Then, glue the root to the wing.
USER MANUAL 35
Wings Assembly
Insert the aileron using 25x20mm polyester hinges or ones made from
another material, similar to the elevator. Then, using a slightly heated
soldering iron, attach M3 threaded inserts designed for servo cover
mounting. Set the servo so that the control horn protrudes through
the opening in the servo cover, glue it in place using hot glue, and
cover it. Then, connect the servo to the aileron using a pushrod.
USER MANUAL 36
Wings Assembly
Prepare the 12x460mm and 6x680mm carbon tubes, which serve as spars
passing through the fuselage. Slide the wings on and route the servo cables
into the fuselage.
USER MANUAL 37
Wings Assembly
M3 screws
The wing assembly is simple and quick. After pushing the wings
against the fuselage, screw in two M3 screws into the designated
places. The screws are anchored in PETG-printed material, making
the system durable and resistant to repeated wing disassembly
USER MANUAL 38
Finishing Build
Now, organize the rest of the equipment. The remaining space in the
fuselage is very spacious and can easily accommodate all the
necessary equipment: FC, ESC, GPS, receiver, and more. After placing
all the equipment, balance the aircraft by positioning the center of
gravity 60mm from the leading edge, measured from the wing-
fuselage junction. You can support the aircraft at this point with your
fingers or other supports and adjust the battery placement to
achieve the proper balance.
USER MANUAL 39
Before Flight
Before takeoff, ensure that the direction of the aileron deflection and
propeller rotation is correct. For this design, the best way to launch is
by throwing it with both hands backward behind your back while
holding it wide by the leading edge. The launch technique is
demonstrated in the flight videos available on the product page.
Good luck with your flights!
