(Diagram shows a close-up of the push rod connection to the aileron control horn, highlighting the arc-shaped adjustment section.)

Transmitter Instruction

The transmitter features various controls:

• One-key Aerobatics Button: For performing aerobatic maneuvers with a single button press.
• One-key Turn around Activation / One-key Return Switch: For initiating a 180-degree turn.
• Throttle: Controls the motor speed.
• Rudder: Controls yaw (left/right movement of the tail).
• Rudder Trimmer: Fine-tunes the rudder's neutral position.
• LED Indicator: Shows status information.
• Gyro Switch: Selects gyro assist level (Off, Mid, Beginner).
• Elevator Trimmer: Fine-tunes the elevator's neutral position.
• Elevator: Controls pitch (up/down movement of the tail).
• Aileron: Controls roll (tilting the wings).
• Aileron Trimmer: Fine-tunes the aileron's neutral position.
• ON/OFF Switch: Powers the transmitter on/off.

(Diagram shows a top-down view of the RC transmitter with labels pointing to each control.)

Gyro Switch

The T-28 Trojan is equipped with a gyro system to aid in stable flight. The switch has three positions:

• 0 - Away From You: Manual / Gyro Off (EXPERT)
• 1 - At the Middle: Soft Gyro Assist (MIDD)
• 2 - Towards You: Strong Gyro Assist (BEGINNER)

It is strongly recommended to turn on the gyro while flying the airplane.

(Diagram shows a close-up of the gyro switch on the transmitter, indicating the positions.)

Binding Instruction

Binding is the process of programming the receiver to recognize the GUID (Globally Unique Identifier) code of a specific transmitter. Once bound, the receiver will only respond to that transmitter.

To Rebind:

1. Keep the transmitter switched OFF, with the throttle joystick at the bottom position.
2. NOTICE: Keep the Gyro switch at the Middle or Beginner position.
3. NOTICE: Keep the plane still in a calm environment for gyro calculation.
4. Connect the battery to the plane, then turn on the transmitter within 5 seconds.
5. The receiver LED will flash for 3-8 seconds to bind automatically.
6. When the receiver LED stops flashing, the binding process is complete.

To Operate a Bound Plane:

1. Power on the transmitter first.
2. Connect the battery to the plane within 3 seconds.
3. The receiver LED in the plane will flash and then turn solid in several seconds.
4. Switch the Gyro control stick to the desired assist level (MIDD or BEGINNER).
5. NOTICE: Allow the airplane to remain still for about 3-5 seconds in a calm environment when first turning on the gyro, to calibrate and activate it. When the gyro starts to react, it is activated.
6. Turn the throttle stick up to the maximum position and then down to the minimum to arm the motor.

CAUTION: Do NOT operate around people or property, otherwise it may cause serious damage!

Throttle Unlock (Arming)

To prevent accidental motor activation, the throttle channel is locked each time the transmitter is powered on. Follow these instructions to unlock the throttle:

CAUTION: Keep the propeller at a safe distance for your safety.

1. Turn the throttle stick up to the maximum position until you hear a "beep" sound.
2. Then, turn the throttle stick down to the minimum position until you hear another "beep" sound.
3. The throttle is now unlocked.

Digital Trims

Digital trims allow you to adjust the centered position of the rudder or elevator surfaces. Each time a trimmer is moved, the servo output changes by one step. If the trimmer is held, the output will scroll in that direction until the trimmer is released or the output reaches its end. When you hear a short "beep" sound, it indicates the trimmer is centered.

(Diagram shows close-ups of the transmitter's elevator and rudder trim controls.)

Channels Reactions Checking

Place your plane in a neutral position. Follow the steps below to check the channel reactions:

• Move the sticks (except the throttle stick) to see if all servo surfaces react correctly as shown in the left diagram.
• Swing your plane to check if all servo surfaces react correctly as shown in the right diagram.

(Diagrams illustrate transmitter stick movements and the corresponding reactions of the control surfaces, including gyro reaction.)

One-key Aerobatics Instruction

The one-key aerobatics feature allows beginner pilots to perform aerobatic actions by simply pressing a button on the transmitter. During flight, with gyro control mode active, press the one-key aerobatics button. The transmitter will beep several times. While beeping, move the aileron stick in either direction for an auto-roll, or move the elevator stick in either direction for an auto-flip.

(Diagram shows the transmitter with the "One-key Aerobatics" button highlighted.)

One-key U-turn Instruction

The T-28 Trojan Warbird features a one-key turnaround function that enables the plane to turn 180 degrees to the opposite direction of flight with a button press.

To Activate:

1. Place your plane heading in the take-off direction.
2. Do NOT unlock the throttle. Press and hold the activation button for several seconds until you hear a "beep" sound. The rudder surface will move, indicating the one-key return function is now activated.

NOTICE: This function must be activated each time you power on the plane.

To Use During Flight:

Press the turnaround switch. The plane will automatically turn around.

To Quit:

Press the switch button again, or move any servo stick (rudder/elevator). The plane will immediately return to your control. Whether flying manually or with gyro assist, activating the one-key return function automatically switches the plane to gyro assist mode for stable flight. Releasing the function returns the plane to its previous control mode.

CAUTION: This is not a "coming home" function; it only performs a U-turn.

Gyro System Calibration

1. Turn the throttle stick to the minimum position.
2. Power on the transmitter and the receiver.
3. Do NOT unlock the throttle.
4. Hold the sticks as shown in the picture for several seconds.
5. When you hear a "beep" sound, the gyro system is calibrated based on the horizontal level you are holding it.

Setting Control Stick Direction:

If the direction of the control stick input has been reversed, proceed as follows:

1. Switch on the control – do not unlock the throttle.
2. Move the control stick to the stop until a tone is heard.
3. The direction of action is now reversed.

(Diagram shows the transmitter with sticks in a specific position for calibration.)

Propeller Saver Instruction

The propeller saver protects the propeller from damage and prevents over-current to the electronic components. If the airplane hits an obstacle, the propeller will detach from its base. To reattach the propeller, insert the upper part centrally through the motor shaft. You will hear a "click" sound when it is securely fastened.

(Diagram illustrates the propeller saver mechanism, showing the base and upper part.)

Propeller Replacement

Follow these steps to replace a broken propeller and shaft adapter. You will need a Philips screwdriver and pliers (not included).

1. Remove the spinner and propeller by loosening the screw with a Philips screwdriver.
2. Carefully remove the shaft adapter. If it is too tight, use pliers to help.
3. Replace any broken parts.
4. Install all parts back in reverse order to complete the replacement.

(Diagram shows the propeller assembly and the tools needed for replacement.)

Flight Checklist

NOTE: This checklist is not intended to replace the full content of this instruction manual. Although it can be used as a quick start guide, it is strongly suggested that you read the entire document completely before proceeding.

• Always turn the transmitter on first.
• Ensure the throttle control stick is at the bottom position before connecting the battery.
• Check all control functions for correct functionality before flight.
• Fly the model (hand-launch or take off from a flat/level surface).
• Land the model (on a flat/level surface).
• Unplug the battery from the ESC.
• Always turn off the transmitter last.
• Remove the battery from the model.

Find a Flight Field

Due to its size and weight, this plane is considered a "park flyer." A local park, schoolyard, or flying field that is large enough and free of people and obstructions is ideal. An area the size of a football/soccer field is recommended, especially for learning. Avoid flying in parking lots, crowded neighborhoods, or areas with people or obstructions.

Flying over grass is recommended as it is a more forgiving surface, causing less damage in case of a crash. Short grass is better for takeoffs and landings; too-long grass can cause the airplane to nose-over or flip. An ideal flying area allows for takeoffs and landings on a smoother surface (like asphalt) and flying over grass.

Fly in spacious areas without obstacles and large plants. Never fly near highways, railways, high-tension lines, crowded areas, or residential zones.

NOTE: The plane is designed for outdoor use only.

(Diagram shows an aerial view of a park-like area with flight paths, and another diagram showing hazards like power lines and crowded areas to avoid.)

Flying Conditions

It is best to fly on calm days without wind, especially when learning. Fly only in calm conditions until you are familiar with the controls and handling. Even light winds can make learning more difficult and may carry the model beyond your line of sight.

For first-time or low-time pilots, it is highly recommended that an experienced pilot test-fly and trim the model before your first flight. A well-trimmed model is easier and more enjoyable to fly.

After you have properly trimmed the airplane in calm conditions and become familiar with its handling, you can fly in light winds or, depending on your experience, in winds up to 5-7 mph.

Do NOT fly on days with significant moisture, such as rain or snow.
