4. Settings for the first flight
Centre of gravity: 65-70mm (measure from the leading edge of the wing to the back)
Ailerons (measure near fuselage)
Flaps negative (start, speed) (measure near fuselage)
Flaps negative (cross-country) (measure near fuselage)
Flaps positive (thermal 1) (measure near fuselage)
Flaps positive (thermal 2) (measure near fuselage)
www.pcm.at 4
FW5 FloW Building Instruction Juni 2010
Landing position (measure near fuselage)
Snap Flap (measure near fuselage)
Rudder (measure at deepest point)
EWD (Difference in angle of attack between wing and elevator) for first flight:
Elevator parallel to axis of fuselage, slightly pulled.
Don’t make a SAL-start at your first flight. Hold the glider on the fuselage and throw it gently.

ASSEMBLING THE MODEL
General information on DLG-models
DLG-models are constructed strong enough to withstand the demands of starting, flying and landing
and at the same time light enough to achieve the least possible flying weight. Each part is
dimensioned to its possible minimum and produced using lightest and fewest material.
In order to continue this concept, please account the following when you assemble the model:
- Always use glue sparingly. Grind all gluing spots thoroughly, before you apply the glue.
- Electronic components should be placed as far as possible to the front, as you normally need
additional lead in the nose of the fuselage to achieve the necessary centre of gravity.
- For the same reason try to save weight especially when you finish and mount the stabilizer.
- If you don’t have any experience in working with resin or if you prefer an easier method, you can
combine the carbon rovings and glass fibre with super glue: Put some drops of super glue on
the rovings or the fibre, spread and press it with a (rustling) plastic bag. You will also save one or
the other gram with this method.
As FW5 FloW has developed from the Fireworks-family, you will find some pictures of Fireworks 4 and
also Mini-Fireworks in the following instruction. Don’t let yourself be confused by this, the way of
building described is quite the same.

5. Installation of the CFR-stab
Sand the rudder wedge-shaped on the hinge line, so that
you can move it in both directions. Note that the hinge line
must be placed on the left side (looking towards flight
direction) for right-handers and the other way round for left-
handed persons.
Next, glue the lever in extension of the axis of the boom. The
hole of the lever should be above the hinge line.
Before you fix the control surface of the rudder with adhesive
tape, put some UHU-por on the gluing spots to improve the
gluing force of the tape.
Spread the UHU-Por with your finger.
www.pcm.at 7
FW5 FloW Building Instruction Juni 2010
Fix the rudder with 2 small stripes of tape to keep it in the
right position. (As soon as you have applied the tape on the
UHU-por, you can’t remove it anymore without destroying the
surface.)
Now you can apply the adhesive tape.
5.1 Torsion spring for rudder
Bend the wire according to the drawing below. Then, tip
back the control surface of the rudder completely. Stick the
spring into the rudder, one end into the unmoved part, one
end into the control surface near the lever.
Then harden the spots with super glue.
Fix the carbon rod (2mm) with superglue in the rudder.
Now you can mount the elevator.
The elevator will keep the distance between the two carbon
rods. If you move the spring without the elevator mounted,
the spring may disappear inside the rudder. Only when the
elevator is mounted, the spring will move along the track cut
out.
Nevertheless, check the elevator for free movability. If
necessary, enlarge the hole in the rudder.

FW5 FloW Building Instruction Juni 2010
Push the rudder (first for a test) into the oval end of the
boom as far as it will go. Before you do so, thread the kevlar
wire into the fuselage. Grease the wire to avoid that it will
also be glued.
Then check, if the stabilizer is aligned correctly on each
axis.
Now glue fuselage and rudder with thin super glue, where
they touch each other.
You should enforce the join between boom and rudder
additionally with a thin carbon roving, which you glue with
thin super glue.
Stick the 2 halves of the elevator to each other on the
leading edge with an adhesive tape to avoid unintended
demounting during start or flight.

FW5 FloW Building Instruction Juni 2010
5.2 Connection of the wire
Now you can hook in the kevlar wire into the lever.
Make a loop, twist the end and fix it with a drop of super
glue.
Note: Don’t use a shrinking tube, as the kevlar wire could be
damaged by the high temperature during shrinking.
Drill a hole in the boom to lead the wire inside the fuselage
to the servo.
