Quote: "INTRODUCTION Thank you and congratulations for purchasing the Top Flite Gold Edition Focke-Wulf 190 D9. If you haven’t yet spent much time studying the Focke-Wulf, you will soon come to realize that, although at a first glance it appears to be a rather conventional appearing plane, in actuality the Focke-Wulf has some very interesting lines and features. And the D model (a stretched version of its predecessor' the A) is the most interesting Focke-Wulf with the extended nose and aft 'fuse plug'. If you’re not already a big fan of the Focke-Wulf, after a while it will begin to grow on you.

This 1/7th scale Top Flite Gold Edition model is an ideal plan-form with long nose and tail moments and adequate wing area - perfect ingredients for a smooth flying plane no matter what the type. In spite of its interesting lines, building this kit is rather straight-forward. Though the fuse is sheeted in several sections, none of the contours should present any difficulty for the average modeler (especially since the sheeting is only 1/16 thick). In the wing, pneumatic retract installation is straightforward with suggestions on air line routing and other details. The characteristic extra long landing gear struts, and the structural problems they present, have been addressed by slightly shortening the struts and by reinforcing the landing gear area with 1/8 birch ply landing gear webs.

With this kit you can achieve whatever level of detail you like. Just by following the instructions and finishing the plane in a scale-looking trim scheme, beginning scale modelers will end up with a model that very much represents a full-size Fw 190D. Experienced builders will find ways to add even more detail, making this Top Flite Gold Edition kit competitive in scale competition.

Your Top Flite Gold Edition Focke-Wulf is intended for scale and general sport flying including mild aerobatics such as loops, stall turns, rolls, etc. Its structure is designed to withstand such stresses. If you intend to use your Focke-Wulf for more rigorous types of flying such as racing or aggressive aerobatics, it is your responsibility to reinforce areas of the model that will be subjected to the resulting unusually high stresses.

DECISIONS YOU MUST MAKE

ENGINE SELECTION: Recommended engine size:
.61 to .75 cu. in. [10.0 - 12.0cc] 2-stroke or
.70 to .91 cu. in. [11.5 - 15.0cc] 4-stroke

Your Focke-Wulf will fly well with any of the recommended engines. 4-stroke engines and most .75 cu. in. 2-stroke engines will turn a larger prop at lower RPM. This is often desirable for scale realism. However, many .61 cu. in. 2-stroke engines produce about as much horsepower as .75 2-stroke and will fly the Focke-Wulf extremely well. If you use a .61 2-stroke engine, a ball bearing, Schnuerle-ported engine is recommended. Our flying prototype flew on an O.S.® MAX .61 FX. This engine provided excellent performance and more than enough power. Although larger engines may be used, the extra horsepower is not needed.

The included adjustable engine mount will hold a range of engines from .61 cu. in. 2-stroke through .91 cu. in. 4-stroke.

EXHAUST SYSTEM: A Top Flite header and muffler are available that will fit inside the cowl. They are designed for 2-stroke engines mounted inverted as used on the model and shown in the instructions. Headers for: O.S.® .61SF, SX - TOPQ7920 SuperTigre® .61-.75 K series (muffler bolts go through the muffler and screw into the engine) - TOPQ7925 SuperTigre .61-.75 G series (muffler bolts go through the engine and screw into the muffler) - TOPQ7926 .61-.75 Warbird In-Cowl Muffler, TOPQ7915

There may be other exhaust systems that will work with this model. If you prefer to use another exhaust system, consider any modifications that may have to be made to accommodate it. It may be helpful to get your exhaust system as soon as possible and place it over the plan to visualize how it will fit. This will minimize delays when you get to that point.

FIXED GEAR OR RETRACTS: You may build your Focke-Wulf with either fixed or retractable landing gear. The pre bent landing gear wires are included to build the kit with fixed gear. Should you decide to install retracts, detailed instructions are provided. The Gold Edition Focke- Wulf is designed to accept the Century Jet Models’ #39025 pneumatic retracts. You may use other retractable landing gear systems but it is up to you to make any modifications necessary. A micro servo was used in the prototype to operate the air control valve. A standard servo could be used for this, but will take up a bit more room.

These items are required for retractable landing gear: CJM Focke-Wulf retractable landing gear (CJMQ3072) Robart #164G Hand Pump with Gauge (ROBQ2363) Williams Bros. #143 3-3/4" Smooth Contour Wheels (WBRQ1143) Servo for the air control valve (micro or mini servo preferred) Light weight glass cloth to reinforce wing sheeting in wheel wells (HCAR5000) (8) #6 x 1/2" screws (GPMQ3160, pkg. of 8) These items are required for fixed landing gear: 3-3/4" Main Wheels (4) 3/16" wheel collars (GPMQ4308)

FLAPS: The Focke-Wulf is designed to incorporate scale split flaps; however, flaps are optional and not necessary for an excellent flying experience. Without flaps, the takeoff roll is longer and the landing speed is faster. Flaps are not difficult to build, but they do require good craftsmanship to fit well. Flaps add nicely to the model’s flight characteristics and scale appearance, and are highly recommended for those who wish to install them. You will find additional information on the use of the flaps in the Flying section near the end of this manual.

For Flaps, you will need the following additional items: Two standard servos (1) Y-connector (HCAM2500 - Futaba® J) (6) Small Pivot Point Hinges (GPMQ4001, pkg. of 15)

COCKPIT AND PILOT: Your model won’t be complete without the Top Flite Focke-Wulf Cockpit Kit (TOPQ8411). It includes the floor, side panels, instrument panel, seat, headrest and hardware. The cockpit kit can be installed after the fuselage is completed, but is easier to install if you have it on hand during construction. Should you choose not to install the scale Top Flite Cockpit Kit, you could leave the cockpit empty or make your own cockpit from balsa or thin cardboard (from cereal boxes.) Top Flite also offers a 1/7 scale WW II American Full Body Pilot (he could be painted in German flight gear!). The order number is TOPQ9000.

TRIM SCHEME: The model on the kit box was covered with dove gray Top Flite MonoKote® film, then painted with Testors Model Master Acrylic paint followed by a clear-coat of Top Flite LustreKote flat clear. A painted finish is the only way to reproduce the spray painted camouflaged 'patchwork' trim schemes found on full-size Focke-Wulfs. If you do decide to paint your model, the balsa skin must first be covered either with MonoKote film, glass cloth and resin, or another type of covering. Refer to the Finishing section near the back of the manual for more details that may help you decide how to finish your model. Since you don’t have to finish it today, there is time to seek the advice of experienced builders in your club who can give you tips on how to prep, cover and paint a balsa model.

If you prefer not to do the work required of a painted trim scheme, you may find a simpler scale trim scheme, or make up your own scale-appearing trim scheme simply by covering the Focke-Wulf with a few of the flat military MonoKote colors such as dove gray, olive drab, cream, tan, sky blue, insignia blue and black.

COMPETITION-MINDED MODELERS: The outline of the Top Flite Gold Edition Focke-Wulf D9 was derived from three-view drawings, photos and highly detailed static kits. Some areas of the outline have been slightly changed to improve flight characteristics. Notably, the area of the tail feathers has been increased to improve directional stability and control. The landing gear struts have been shortened slightly to improve handling and durability, and do not retract fully into the wing, but protrude below the wing approximately 1/8 in.

The approximate scale of this model is 1:6.5.

If you plan to enter your Focke-Wulf in scale competition (it’s lots of fun, and the runways are usually paved!), this kit may be entered in Fun Scale, Sportsman Scale and Expert Scale classes in AMA competition. All classes have the same flight requirements in which you must perform ten maneuvers, five of which are mandatory. The other five are up to you - easy stuff like a slow, low inspection pass with flaps extended, or maybe a touch-and-go. If you have never competed in a scale contest, you could start out in Fun Scale. In Fun Scale, the only documentation required is any proof that a full-size aircraft of this type, in the paint/markings scheme on your model, did exist. A single photo, a kit box cover from a plastic model, or even a painting is sufficient proof..."
