Transmitter Instructions

TOP-Gyro Switch

• 0 – Away From You-manual/ TOP-Gyro Off(EXPERT).
• 1 – AT the Middle-soft TOP-Gyro Assist(MIDD).
• 2 – Towards You- Strong TOP-Gyro Assist (BEGINNER). This airplane comes with a pre-installed TOP-Gyro device to help make the flying of this model easier. The TOP-Gyro system offers 3 levels of assistance. With the switch in Position 0 (away from you) there is no Gyro assistance. This position is only recommended for experienced or Expert fliers.
• Position 1 (Midd switch position) offers soft self levelling assistance for new to intermediate fliers.
• Position 2 (Beginner switch position, closest to you) offers the strongest level of assistance for the new flier. This position will strongly assist the model to stay level and fly easily.

CAUTION: It is strongly suggested to use Position 2 or 1 when you first fly this model. As you become more experienced you can progress from 2 to 1 to 0. The TOP-Gyro switch position can be changed whilst flying so if you are having difficulties we suggest to move the switch to Position 2. Note that the Calibration of the TOP-Gyro system as described on page 7 MUST be performed before the very first flight of this model.

Binding Instruction

Your model is shipped from the factory w ith the transmitter bound to the receiver.
Binding is the process of programming the receiver to recognize the GUID(Globally Unique Identifier)code of a single specific transmitter. When a receiver is bound to a transmitter, the receiver will only respond to that specific transmitter.
If you need to rebind for any reason, please follow these steps:

1. Keep the transmitter switch OFF, throttle joystick at bottom position NOTICE: Keep Top-Gyro switch at Middle or Beginner position
   NOTICE: Keep the plane still in a calm environment for calculating the Top-Gyro.

2. Connect the battery to the plane, then turn on the transmitter within 5 seconds.

3. The receiver LED will flash for 3-8 seconds to bind automatically.

4. After the receiver LED stop flashing, it means the binding process is done.

Follow below steps when you operate a bound plane.

1. Power on transmitter first.
2. Connect the battery to the plane within 3 seconds.
3. The receiver LED in plane will flash and then tum to solid in several seconds.
4. Switch the Top-Gyro control stick to Top-Gyro assist level (MIDD or BEGINNER). NOTICE: Allow the airplane stay still about 3-5 seconds in a calm environment when you first time turn on Top-Gyro, in order to calibrate and activate the Top-Gyro When the Top-Gyro starts to react, means it is activated.
5. Turn throttle stick up to max and then down to min to arm the motor.

CAUTION: Do NOT operate around people or property, otherwise it may cause serious damage!
For safety reasons, every time when you turn on the Transmitter, the throttle will be locked, follow these steps to unlock the throttle.

Note: Just keep distance from the propeller for your safety.
Turn throttle joystick to the Max position, until you hear the “beep” sound, then turn the throttle joystick to the lowest position, until you hear the “beep”, then the throttle is unlocked.

Digital Trims

Digital trims allow you to adjust the centered position of aileron, rudder or elevator. Each time when a trimmer is moved,the servo output will change one angle. 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 means the trimmer is centered.

Channel Reaction Checking

Place your plane in a neutral level position, follow below steps to check the channels reaction. Move the sticks (except the throttle stick) to see if all servo surfaces react correctly as shown in the left diagram (left throttle for example). Swing your plane to check if all servo surfaces react correctly as shown in the below diagram.

Mode 2 (Left Throttle ) Shown

One-key Aerobatics Instruction

The one-key aerobatics feature allows beginner pilots to perform aerobatic actions by simply pressing the button on transmitter.
During flight, under Top-Gyro control mode, press the one key aerobatics button, the transmitter will beep several times. During the beeping, simply move the aileron stick to either direction for auto-roll. Or move the elevator stick to either direction for auto-loop.

One-key U-turn

The airplane comes with one-key U-turn function, which enables the plane to U-turn by the opposite direction that the airplane takes off. Follow below steps to activate the function.

1. Place your plane heading to the take-off direction.
2. Do NOT unlock the throttle , press the activation button and hold for several seconds until you hear a ” beep ” sound , the rudder surface will respond , meaning the one-key U-turn function is now activated.

NOTICE
Every time when you power on the plane, it requires to activate the one-key U-turn function. To use this function during flight , press one-key U-turn switch button , the plane will turn around automatically back to the opposite direction where it takes off. To quit, just press again the switch button, or control any servo stick (rudder / elevator), the plane will back to your control immediately. No matter you fly the plane under manual control or Top- Gyro assist mode, when you turn on the one-key U-turn function, the plane will enter Top-Gyro assist mode automatically to help stably flying back. When you quit this function, the airplane will back to what the control mode it was.
CAUTION: This function is bound to the receiver, instead of to the transmitter, which means the plane Will U-turn ONLY to the opposite direction that the plane takes off. It also means when the plane U-turns and passes the position where you activated the function, the one-key U-turn function will NOT U-turn the plane back to the take-off position.

Top-Gyro System Calibration

1. Place the model on a flat horizontal surface.
2. Turn the throttle stick to min position.
3. Power on the transmitter and the receiver.
4. Do NOT unlock the throttle.
5. Keep the sticks as above picture for several seconds.
6. When you hear a ” beep ” sound, it means the Top-Gyro system is calibrated based on the horizontal level you are keeping it.

• This process should be performed before the very first flight of the model.

Propeller Saver Instruction

The propeller saver keeps the propeller from damage, and prevent the electronic components from high current loads.
When the airplane hits any obstacles, the propeller will come loose from its mount. To install the propeller back to the base, insert the prop adaptor centrally through the motor shaft, and hearing a “click” sound to ensure it is secured.

Propeller Replacement

Follow below steps to replace broken propeller. You will need help of a Philips screw driver and pliers (not included).

1. Take off the spinner and propeller, by loosening the screw with a Philips screw driver.
2. Take off the prop adaptor carefully. If it is too tight, use pliers to help.
3. Replace any part broken.
4. Install all parts back by inverted orders to finish the replacement.
