PAIRING TRANSMITTER AND RECEIVER
Step 1
Set up the drone level and insert the Li-Po battery as shown in the
illustration. Switch the drone on and do not move it until the LED changes
from fast to slow flashing. Now the remote control can be paired with the
drone.
Step 2
Turn on the drone first, then the controller. The controller will emit a beep
tone when it is turned on.
The LED of the drone will change from flashing to solid, indicating that the
controller and the drone are now paired.
If the transmitter is not to be used for a longer period of time, remove the battery for storage.
Step 3
Remove the drone’s battery after a flight.
Develop correct habits so as not to cause security risks.
Warning: If the battery is not removed from the drone for a long period
of time, it may be damaged due to over-discharge, or even become a fire
hazard.
Step 4
Turn off the transmitter. If the transmitter is not to be used for a longer
period of time, remove the batteries for storage.
Warning: If the AAA batteries are left in the transmitter, potential
leakage may occur which may damage the transmitter, and create fire hazards.
FLIGHT ADJUSTMENT AND SETTING
Read all instructions carefully before flying.
- Place the aircraft in an open field with the tail pointing in your direction.
- Practice operating the throttle stick (as below illustration).
TRIM
Slowly raise the throttle to lift off. If it tends to a different direction,
use the Trim button for correction.
Forward and backward trim.
-
When the aircraft is starting to take off and it drifts forward/backward.
When drifting forward, adjust the Trim button to rear until it is balanced
When drifting backward, adjust the Trim button to forward until it is balanced.
Leftward and rightward trim -
When the aircraft is starting to take off and it drifts left /right.
When drifting leftwards, adjust the Trim button to the right until it is balanced.
When drifting rightwards, adjust the Trim button to the left until it is balanced.
RECALIBRATION
If the trim buttons do not correct the problem, place the drone on a flat
surface and recalibrate as follows.
Press the calibration button; the LED on the drone will start flashing. Wait
until the indicator stops flashing. It is now completed.
HEADLESS MODE
When syncing, the antenna of the transmitter must be aligned with the tail of
the quadcopter.
In normal flight, when pressing the headless button, two beep tones are
emitted and the LED flashes. Press this button again, to exit headless mode; a
beep tone is emitted.
ONE-BUTTON RETURN
When the quadcopter is flying far away, the one-button return can recall the
quadcopter. After pairing the quadcopter, the antenna of the transmitter must
be aligned with the tail of the quadcopter at take-off. Press the one-button
return button to access return mode; the LED flashes. Press the button again
to exit return mode. When returning, the forward and backward movement of the
right joystick will interrupt this function.
HIGH SPEED AND LOW SPEED
The default speed is low speed. Press the button to switch to medium speed,
press again to switch to high speed.
3D FLIP
When you are familiar with basic flight operations, you can do some awesome
and exciting tricks and stunts! First of all, fly the aircraft to a height of
more than 3 meters, press the 3D button on the rear right side of the
transmitter, then push the right rudder (in any direction) to make a
360-degree flip.
