Center Control Surfaces
If the rudder is angled off to the right or left, adjust
the push rod by its arc-shaped section slightly,
making sure the rudder is properly centered.
NOTE: Keep the X-PILOT switch off (manual mode) before you operate the steps below. See more
information in "X-PILOT switch" section.
With the transmitter turned on and the battery conected to the ESC(and installed in the battery
compartment), it is now possible to check the center of all control surfaces.
Observe the rudder to ensure it is properly centered as shown above.
Then observe the elevator to ensure it is properly centered as shown above.

- The airplane comes with pre-installed X-PILOT to help
control ying easily.
- The switch is with 3 levels to control the X-PILOT. To turn
on the X-PILOT, switch to upper position (towards you).
- To turn off the X-PILOT, switch to lower position.
(away from you).
CAUTION: It is strongly suggested to turn on X-PILOT while
ying the airplane.
To prevent from damages, the throttle channel is locked each time when powering on your transmitter.
Follow below instruction to unlock the throttle.
CAUTION: Keep the propeller in distance for your safety.
Turn the throttle stick up to max position until you hear a "beep" sound. Then turn the throttle stick down to
min position until you hear a "beep" sound.
Now the throttle is unlocked.
Binding is the process of programming the receiver to recognize the
GUID (Globally Unique Identier) code of a single specic transmitter. When a receiver is bound to a
transmitter, the receiver will only respond to that specic transmitter.
If you need to rebind for any reason, please follow these steps:
1.Keep the transmitter switched OFF, throttle joystick at buttom position.
NOTICE: Keep X-PILOT switch at Middle or Beginner position.
NOTICE: Keep the plane still in a calm environment for calculating the X-PILOT.
2.Connect the battery to the plane, then turn on the transmitter within 5 seconds.
3.The receiver LED will ash for 3-8 seconds to bind automatically.
4.After the receiver LED stop ashing, it means the binding process is done.
Follow below steps when you operate a bound plane:
1.Power on transmitter rst.
2.Connect the battery to the plane within 3 seconds.
3.The receiver LED in plane will ash and then turn to solid in several seconds.
4.Switch the X-PILOT control stick to X-PILOT assist level(MIDD or BEGINNER).
NOTICE: Allow the airplane stay still about 3~5 seconds in a calm environment when you rst time turn
on X-PILOT, in order to calibrate and activate the X-PILOT. When the X-PILOT 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!

Trimmer
Digital trims allow to adjust the centered position
of aileron, rudder or elevator hinge. 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.
Place your plane in a neutral position, follow below steps to check the channels reactions.
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 right diagram.
The one-key aerobatics feature allows beginner pilot to perform aerobatic actions by simply pressing the
button on transmitter. During ight, under X-PILOT 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-ip.

The airplane comes with one-key U-turn function, which enable 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 ight, press the 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 ies the plane
under manual control or X-PILOT assist mode, when
you turn on the one-key U-turn function, the plane will
enter X-PILOT assist mode automatically to help
stably ying back. When you quit this function, the
airplane will back to the 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.
1.Turn the throttle stick to min position.
2.Power on the transmittaer and the receiver.
3.Do NOT unlock the throttle.
4.Keep the sticks as above picture for several seconds.
5.When you hear a “beep” sound, it means the X-PILOT system is
calibrated based on the horizontal level you are keeping it.
The propeller saver keeps the propeller from damage,
and prevent the electronic components from over
current. When the airplane hits any obstacle, the
propeller will loose from the base. To install the
propeller back to the base, insert the upper part
centerly through the motor shaft, and hearing a "click"
sound to ensure it is secured.
