ank you for choosing the FOCKE-WULF FW190 ARF by SG MODELS . e FOCKE-
WULF FW190 was designed with the intermediate/advanced sport yer in mind. It is a semi
scale airplane which is easy to y and quick to assemble. e airframe is conventionally built
using balsa, plywood to make it stronger than the average ARF, yet the design allows the aero-
plane to be kept light. You will nd that most of the work has been done for you already.
e motor mount has been tted and the hinges are pre-installed. Flying the FOCKE-WULF
FW190 is simply a joy.
is instruction manual is designed to help you build a great ying aeroplane. Please read this
manual throughly before starting assembly of your FOCKE-WULF FW190 . Use the parts

Because the size of servos dier, you
may need to adjust the size of the precut
opening in the mount. e notch in the
sides of the mount allow the servo lead to
pass through.
1) Using a small weight (Weighted fuel
pick-up works well) and string, feed the
string through the wing as indicated.
2) Place the servo between the mounting
blocks and space it from the hatch. Use a
pencil to mark the mounting hole loca-
tions on the blocks.
3) Use drill bit in a pin vise to drill the
mouting holes in the blocks.

4) Apply 2-3 drops of thin C/A to each
of the mounting holes. Allow the C/A to
cure without using accelerator.

5) Use dental oss to secure the connec-
tion so they cannot become unplugged.

8) Remove the string from the wing at
the servo location and use the tape to at-
tach it to the servo extension lead. Pull
the lead through the wing and remove
the string.
6) Secure the servo to the aileron hatch
using Phillips screwdriver and the screws
provided with the servo.
7) Apply 1-2 drops of thin C/A to each of
the mounting tabs. Allow the C/A to cure
without using accelerator.

9) Set the aileron hatch in place and use a
Phillips screw driver to install it with four
wood screws.

OPTIONAL ELECTRIC RETRACT
LANDING GEAR 33cc.
Electric retract landing gear is not in-
cluded in this kit, however it is a very
popular add-on as optional. If you want
to use retracts in your FW190, we recom-
mend that you buy a good set of electric
retracts as the Himark AM07 Main Gear
shown as below. ese retract units will
bolt right into the FW190 inplace of the
standard xed gear.

INSTALLING THE FUSELAGE SERVOS.
.
Because the size of servos dier, you
may need to adjust the size of the precut
opening in the mount. e notch in the
sides of the mount allow the servo lead to
pass through.
1) Install the rubber grommets and brass
collets onto all servos. Test t the servos
into the servo mounts.
2) Secure the servos with the screws pro-
vided with your radio system.

INSTALLING THE STOPPER
ASSEMBLY.
1) Using a modeling knife, carefully cut
o the rear portion of one of the 3 nylon
tubes leaving 1/2” protruding from the
rear of the stopper. is will be the fuel
pick up tube.
2) Using a modeling knife, cut one length
of silicon fuel line. Connect one end of
the line to the weighted fuel pick up and
the other end to the nylon pick up tube.
5) With the stopper assembly in place, the
weighted pick-up should rest away from the
rear of the tank and move freely inside the
tank. e top of the vent tube should rest just
below the top of the tank. It should not touch
the top of the tank.
FUEL TANK INSTALLATION.
You should mark which tube is the vent
and which is the fuel pickup when you attach
fuel tubing to the tubes in the stopper. Once
the tank is installed inside the fuselage, it may
be dicult to determine which is which.
3) Carefully bend the second tube up at a 45º
angle. is tube is the vent tube.
4) Test t the stopper assembly into the tank.
It may be necessary to remove some of the
ashing around the tank opening using a
modeling knife. If ashing is present, make
sure none falls into the tank.

6) When satised with the alignment of the
stopper assembly tighten the 3 x 20mm ma-
chine screw until the rubber stopper expands
and seals the tank opening. Do not over-
tighten the assembly as this could cause the
tank to split.

7) Slide the fuel tank into the fuselage. Guide
the lines from the tank through the hole in
the rewall.

gine and muer. e vent line will connect
to the muer and the line from the clunk to
the carburetor.

Reinstall the servo horn by sliding the
connector over the pushrod wire. Center
the throttle stick and trim and install the
servo horn perpendicular to the servo
center line.
Move the throttle stick to the closed po-
sition and move the carburetor to closed.
Use a 2.5mm hex wrench to tighten the
screw that secures the throttle pushrod
wire. Make sure to use threadlock on the
screw so it does not vibrate loose.
COWLING.
Please see these below pictures.
1) Tape the cowl to the fuselage using
low-tack tape.

Focke- Wulf FW190 Instruction Manual.

2) Use a drill and drill bit to drill the holes
for the cowl mounting screws. Make sure the
cowl position is correct before drilling each
hole.
3) With the muer, needle valve, and spark/
glow plug removed from the engine, slide
the cowl in place over the engine. Temporar-
ily install the propeller and spinner in order
to nd the exact location of the cowl. When
satised with the cowl placement, secure the
cowl to the fuselage using masking tape.
4) Install the muer and muer extension
onto the engine and make the cutout in the
cowl for muer clearance. Connect the fuel
and pressure lines to the carburetor, muer
and fuel ller valve. Secure the cowl to fuse-
lage using the M3x10mm socket head screws.
