Pairing

 

 

Switch on the drone and the LED’s flash waiting for pairing. Place on flat ground about 2m in front of 
you, pointing away from you. 

 

Set the Controller throttle to minimum and then switch 

on the Controller. Drone LED’s will flash rapidly 

and then stay on, the Controller will beep and the Controller LED will flash alternately Red and Green. 

 

Push the throttle smoothly to maximum and then back to minimum. The drone LED will flash off and 

back on, the Controller will stop beeping and the LED will turn green. 

 

WARNING: The next use of the throttle will start the motors.

First time users

 

 

Before you are familiar with the drone, please don’t fly it. Read the instructions carefully. Get familiar 
with all kinds of direction control and keep repeating until you can do it easily. 

 

Practice operating the control of each rocker (each mode of operation as shown) and repeat practice 

throttle high/low, left/right., front/rear and left/right operation. 

 

The simulation flight practice is very important. Please keep practicing until the fingers move naturally.

Flight Adjustment and Trimming

 

 

Ensure you trim the drone for stable flight. This will make flying much easier and more fun. See our video 

How to Trim your Drone for easy flying

 

 

Place the drone in a clear open space with the tail of the drone pointing towards yourself. 

 

Increase the throttle until the drone lifts off. If the drone lifts off vertically without moving in any other direction 

you are good to go. Often with a new drone or after maintenance e.g. propeller change, the drone will not lift 

off straight up but will drift in one direction or another, sometimes more than drifting, in which case you need 

to correct for this. 

 

You will find the trim controls on the Controller drawing above. Each press of the control will reduce the 

tendency for the drone to move in the opposite direction. If the drone is moving forward then click the Trim 

Back button a couple of times and then try and lift off again. 

 

You may have to repeat the above step a few times to cancel out the movement of the drone so it just lifts off 

vertically. 

 

Often the drone doesn’t just drift forward or back or left or right but a combination making it drift diagonally. In 
this case correct either forward/backward first or left/right and then do the other.  

 

Sometimes the drone will lift up and immediately skim along the ground in one direction or the other. Users 

sometimes think there is a problem because the natural reaction is to cut the throttle making the user believe 

it will not actually lift off. You may find you have to apply quite a number of clicks to counteract this. 

To re-calibrate the on-board gyroscope, move both sticks to the lower left position. Hold them there, the controller 

will beep and the drone LED

’s will flash rapidly. When the LED’s stop flashing calibration is complete
