Print out these pages on A4 paper and cut out the templates. For the Aileron, cut them
out along the red dotted line and glue the parts together exactly. Attach them to the foam
board and cut the foam parts with a sharp knife.
IMPORTANT The print must be set to 100% page size, so that the size fi ts exactly!

The development of a complex, airworthy RC flight model to express on any standard 3D printer is a very extensive process. Therefore, we appeal to your fairness
not to forward the STL data you have acquired to third parties.
Thank you for your understanding and have fun with your PLANEPRINT MODEL!
Printing the parts – Printing profiles
This manual is constantly being improved and supplemented, we recommend
downloading the latest version from our website before building.
To print all PLANEPRINT models you need to set some basic profiles in Cura
(If you use another slicer, please set the same parameters).
You can find the description at www.planeprint.com/print
Align the center part using the carbon tubes so that they are correctly
positioned in the body, then remove the tubes and run thin CA glue into all
joint surfaces. These parts must be very well fi xed.
medium liquid
thin liquid
If the carbon tubes are stiff, move them back and forth until the hole is
adjusted. They should be precise but easy to insert. They must not be glued!
This tail version is the simplest and lightest. If you want to build the version with movable feathers,
skip this page.
NOTE For Depron use UHU POR, other adhesives will damage the
material. It is also suitable for other types of foam. UHU POR is a contact
adhesive. Coat both adhesive surfaces (foam and LW PLA) with adhesive
and wait until it is dry. Then join the parts together.
Glue the foam elevator
onto the tail base and
the foam rudder into the
upper part.
To assemble, fi rst
insert the rudder into
the slot at the back of
the elevator and fi x
everything with three
tapping screws.
You can swap the rudder
for another version at
any time.

The glass version is visually less conspicuous than
the foam rudder, but somewhat heavier and less
stabilizing in fl ight.
Fold the rudder at the top and insert it into the
slots of the tail part. Allow thin CA glue to run into
the slots and do not use activator spray to prevent
clouds from forming.
Finally, the two levers are connected to the expandable
elevators. All joints must run absolutely smoothly so as
not to put too much strain on the servo!
The two movable elevator parts touch each other when
the elevator is at the bottom, at the top they are spread
to the maximum. Check the process several times and
make sure that everything works smoothly, the function
of the elevator is essential in fl ight!
If the angles do not fi t, you can print the alternative
levers and try them out.

Cut out the foam parts for the wing (Wing/Aileron) and temporarily fi x
them along the aileron with two strips of adhesive tape. Make sure that
a gap of 1 to 2 mm remains open for the later aileron hinge!

... then fold the foam part over and
apply UHU POR to the wing and
foam and allow the glue to dry.
When the glue is dry, glue the
parts together.
Remove the adhesive tapes and cut a narrow stripe from fabric
(or use a tape for the hinges, it should be paintable).
Wet the fabric strip and the area along the hinge with UHU
POR, let it dry and then glue the strip to the wing and aileron.
The gap allows the outer part to move without a visible aileron.
You can cut off the
aileron servo cable
and solder on an
extension or use
an extension cable.
Because there is little
space in the narrow
wing, the outer sheath
must be removed
(carefully! with side
cutters or a knife).
Cut out two servo covers from fabric
according to this template:
Stick the servo
into the wing with
double-sided
adhesive tape or
wrap it with tape and
glue it with CA glue.
This length must measure exactly 130 mm
Here you can check whether the print is the exact size.
Carefully enlarge this opening
in the servo duct with a knife
until the servo cable plug fi ts
through.
Glue the control horn onto the
aileron as shown in the picture
below and fi nally, if everything
is set up correctly, the fabric
servo cover.
Install the servos as shown in the
picture. Make the servo arms rather
short so that the entire angle of the
servo can be utilized (less load on
the servo)!

There is room for lead in the beak. Position the receiver

When gluing the magnets, make sure that they
are correctly aligned and do not repel each other.
You can put a piece of tape between the magnets
as a separator until the glue is fi rm.

Painting
I sprayed the base with two spray paints
(acrylic), light gray and light beige, very
thinly all over the bird. The plumage
was painted on with a fl at brush and
acrylic paints. Make sure that the paint
is rather dry, this automatically gives a
realistic effect. I used dark brown, a little black for blending and white. Yelloworange for the beak area. The eyes are
simply painted black and then painted
several coats of high-gloss varnish (or
nail varnish).
It is an advantage if you do not use
colors that are too dark, otherwise you
will have to protect the bird from direct
sunlight on warm days (the PLA can
Basic setting It is very important that these settings are correct!
Place the setting gauges on the aileron at the height of the servo on
top of the wing and program the correct zero position. Likewise between body and elevator.
Any deviation
from this setting
changes the entire
wing characteristic!

To start from the hand with the motor version, you
should give about half throttle and only increase the
throttle after a few meters. Despite the large downward correction angle of the engine, the Falcon pulls
up slightly when it gets fast. You have to be prepared
to correct a little with the elevator. We do not recommend a fixed correction program, as the effect becomes more pronounced the faster the bird flies.
Throw it upwards at a flat angle (10 to 20 degrees)
and make sure that it does not have a sideways effect
when released from the hand.
Be careful around the propeller area!
LANDING
The Falcon has the positive characteristic that it does
not stall over the wing in the event of a stall, but
only goes into a descent by turning the nose further
and further down. It still flies even with the elevator
fully pulled. You can recognize this flight condition
by the many small pitching movements, which are a
series of micro-stalls.
It is therefore important for the landing to give a little more speed on the final approach to ensure
enough energy to recover before ground contact.
Especially on a slope, when landing with a tailwind,
you must be careful not to approach too slowly.
WHICH TAIL VERSION IS THE BEST?
The transparent foil rudder looks better than the
foam version, but is much heavier and requires significantly more weight at the front due to the long lever
and short neck of the Falcon. It is also slightly smaller
than the foam rudder and therefore does not stabilize
quite as well.
If you want maximum flying fun, including acro maneuvers, we recommend using the foam rudder.
If the main aim is to get as close as possible to the
image of a real animal, the glasrudder is an advantage.
It can therefore be easily changed at any time with
three screws. But don‘t forget to always pay atten-
tion to the correct CG!
Please be aware of wildlife and fly the Falcon
only in areas where it is allowed!
