Introduction

The F9F-8 Cougar is a swept-wing fighter jet re-developed by the Grumman Company of the United States based on the F9F Panther “Panther” in 1953. This Free wing 1/10 scale F9F-8 Cougar 80mm EDF electric model jet uses EPO material and uses the plastic structure, cabin door and other details. Horizontal tail and Vertical tail uses the screws to fix, main wing uses the newest Free wing assemble structure—quick portable install. No glue or screws to fix, and easy to carry. The Free wing F9F-8 Cougar PNP version includes a preinstalled 80mm EDF power system at 2023, comprising a 12-blade EDF impeller, 3658-2150KV in-runner motor, 100A ESC with reverse thrust function. The new power system provides more powerful thrust, resulting in a top speed of 180 kph/112.5 mph for this aircraft. The Free wing F9F-8 EDF jet uses the main gray paint of the US Navy VF-61 Squadron, with partial yellow and silver patterns, making it also highly recognizable in the sky. This jet has low requirements for flight technology, and is a medium-sized scale basic training jet. The PNP version is pre-installed with a gyro at factory, which can also maintain a stable flight attitude at low speeds in 2-3 wind speeds. The new shock absorbing structure of the landing gear makes the reciprocating motion of the shock absorbing rod more flexible, and the shock absorbing effect is better. The outer diameter of the front and rear wheels of 45mm/50mm enables the aircraft to take off and land on grass. Thank you again! I hope this product can bring you more beautiful flight time!

PNP Assembly Instructions

Install Horizontal Stabilizer
As the photo show:

1. Insert the carbon tube into the vertical tail;
2. Insert one side horizontal tail into the vertical tail, Use the traction metal wire to pull out the servo cable along the vertical tail slot;
3. After installed the horizontal tail, fix it with screw;
4. Repeat the above steps to install the other side of horizontal tail.
   Screw ,I<A3X1Omm 2pcs)
   Carbon tube (04x210mm)

As the photo show:

1. As shown in the photo, after installed the tail set, insert the rudder servo cable and the elevator servo cable into the PCB board at the rear fuselage, the elevator servo cable into the ELE interface, and the rudder servo cable into the RUD interface;
2. Fix the tail set with screws.
   Screw (KA3X1Omm 5pcs)

Install Main Wing
As the photo show:

1. Insert the main wing carbon fiber tube after aligning with point A of the fuselage. Before closing, connect the ribbon wire into the main wing board interface;
2. After the main wing side slot is aligned with the fuselage point B. C, continue to close the main wing and the fuselage;
3. When a slight “click” sound is heard, it is proved that the main wing has been installed;
4. Check to confirm that the latch toggle lever on the wing upper surface of main wing has been reset and locked 0;
5. Repeat the above steps to install the main wing on the other side.

1 Three different states of the latch toggle lever is as the photo shown:
Latch toggle lever lock status
As the photo show, the front/rear lever is in outside end point

When unlocking, it is necessary to manually push the front and rear toggle levers towards the middle at the same time.
Latch toggle lever unlock status
As the photo show, the front/rear lever is in inside end point

The latch toggle lever abnormal status
As the photo show, the front/rear lever is not in outside or inside end points

After installed the main wing, please check carefully. If happen the abnormal status, it is necessary to manually push the latch toggle lever to reset.

Install Drop Tank, Missiles

Install Small Plastic Parts

Before connecting the battery and receiver, please switch on the transmitter power and make sure the throttle stick is in the lowest position. Bind your receiver to your transmitter according to your transmitter’s instruction manual.
We recommend the following LiPo battery: 6S 22.2V 4000mAh-6S 22.2V 5200mAh Discharge rate of C 35C

Pushrod instructions

Important additional notes

The Y-type clevis used in this product is equipped with a transparent silicone ring for secondary reinforcement, which can effectively prevent the clevis from accidentally loosening.
As shown in the following figure, when you buckle the clevis into the control surface horn, use the silicone ring to cover the clevis.

Center of Gravity

Correct Center of Gravity (“CG”) is critical for enabling safe aircraft stability and responsive control. Please refer to the following CG diagram to adjust your aircraft’s Center of Gravity.
– Depending on the capacity and weight of your choosen flight batteries, move the battery forward or backward to adjust the Center of Gravity.
– If you cannot obtain the recommended CG by moving the battery to a suitable location, you can also install a counterweight to achieve correct CG. However, with the recommended battery size, a counterweight is not required. We recommend flying without unnecessary counterweight.

Control Direction Test

After installed the plane, before flying, we need a fully charged battery and connect to the ESC, then use radio to test and check that every control surface work properly.

Dual Rates

According to our testing experience, use the following parameters to set Aileron/Elevator Rate. Program your preferred Exponential % in your radio transmitter. We recommend using High Rate for the first flight, and switching to Low Rate if you desire a lower sensitivity. On successive flights, adjust the Rates and Expo to suit your preference.

| Aileron
(Measured closest to the fuselage)| Elevator
(Measured closest to the fuselage)| Rudder
(Measured from the bottom)| Flaps
---|---|---|---|---
Low Rate| H1/H2 2Orrim/20mm D/R Rate: 80%| H1/H2 24mm/24mm D/R Rate: 80%| H1/H2 17rnm/17mm D/R Rate: 60%| H1 19mm
High Rate| H1/H2 25nnm/25mm D/R Rate: 100%| H1/H2 26mm/26mm D/R Rate: 100%| H1/H2 22nrim/22mm D/R Rate: 80%| H1 28mm

Flight Note:

1. Standard gyro. This F9F has been equipped with gyro. It has been preset with parameters suitable for F9F aircraft flight. You do not need to set the gyro again, but need to pay attention to the use of stability enhancement mode for flight(the red LED light of gyro is always on);
2. Gyro setting: Aileron sensitivity: 40% Elevator sensitivity: 40% Rudder sensitivity: 40% Sensitivity level: medium sensitivity
3. Flap down, the elevator does not need to be trimmed;
4. The elevator needs some upwarp in order for the plane to level off.
   Please refer to the right photo to set the elevator center position.
