The Freewing F9F-8 Cougar 80mm EDF JET is the one that has fascinated me more. I think because it was a relatively new fighter in Russian service when I was a kid which created a certain ere of mystery surrounding it. Plus, as a design, it has a nice look that I've also kind of liked.
The Freewing F9F-8 Cougar 80mm EDF JET is a good sized model that comes well packed and assembles quickly. Assembly begins with installation of the horizontal tail which is held in place by two screws. From there, the wings slide into place over two carbon spars and are held with two screws in each wing. The ventral fins are clipped into place, the model rolled over and the vertical tail installed being held with three screws. Once together, the winglets are clipped onto the wing tips which completes the assembly. The fit of all of the parts was great and the assembly was a breeze.?
With the airplane together on the bench, it is a very nice looking model and the size of it really becomes apparent once together. The paint scheme is a red version of the 70mm which looks good and is well executed as well. There is a nice large canopy hatch with significant space for an assortment of batteries. With the size of the aircraft and the battery space available, Spektrum 6s 7000mah Smart batteries are a no brainer for flight time and performance. :) Lastly, yhe design features a nice clean inlet system which means no auxiliary air grates in the fuselage and translates into greater efficiency in flight.
AIRCRAFT SETUP CG
For the aircraft setup, this is the bind and fly version of which means that it includes SAFE select as well as the full Smart telemetry. If you��re using some of the newer NX radios , setting up SAFE can be simplified through assigning it in the forward programming menus. It requires selecting the desired channel to SAFE and then going into the channel assign menus and assigning that channel to your desired switch for SAFE. This really makes things easy and also allows you to turn on and off AS3X even should you choose.
For the control surface setup, I found that I preferred my mid rates all around which equate to the following deflections:
Elevator �C 12mm up/down with 12% Expo
Aileron �C 12mm up/down with 5% expo
Rudder �C 22mm left/right with 25% Expo
Flaps �C 25mm mid, 45mm full, no elevator mix required
As previously mentioned, Freewing F9F-8 Cougar 80mm EDF JET has a nice large battery area in the forward fuselage which allows for higher capacity batteries to be used for good flight times. While smaller capacity packs can be used, I prefer to fly the model with Spektrum Smart 6s 7000 mah batteries. This easily provides 5 plus minute flight times and the model handles the weight easily.
In terms of the CG, I started with the recommended location is a good place to start. I ultimately moved the CG back a touch which equates to 115mm as measured from the wing root leading edge aft. At this location, the 7000mah battery resides about 1.5�� forward of the receiver mounting plate in the battery area. Note that I��m just CGing the airplane with my fingertips right side up with the gear down and it works easily.
