Learning to fly

 

Throttle Control Practice 

Slowly increase the throttle. When the drone begins to lift off the ground, slowly reduce the throttle to bring the 

drone back down. Keep practicing this action until you can control the throttle smoothly and can stop the drone at 

any height. NOTE: when within 2-300mm off the ground this can be more difficult 

due to the “Ground Effect”. 

Rudder Control Practice 

Slowly increase the throttle to bring the drone into a hover about 1-2m off the ground. Use the rudder to rotate the 

drone left and right. The drone will keep rotating while you apply rudder. To return to the same heading as before 

push the rudder in the opposite direction and release when at the required heading. 

Aileron and Elevator Control Practice 

Slowly increase the throttle to bring the drone into a hover about 1-2m off the ground. Use the aileron, right hand 

joystick, to move the drone to the left. Stop and move the aileron to the right. Bring the drone back in front of you. 

REMEMBER

 to turn off the Controller and switch off the drone and disconnect its battery after use. 

If the controller is not going to be used for a day or more, remove the batteries in case they are forgotten and leak 

which will damage the Controller.

Flying

 

Headless Mode 

Headless mode simplifies flying by eliminating the need to know which way the drone is pointing. No matter 

where the drone points it will follow the forward, left, right and back of the controller relative to the operator. 

Push in on the left-hand joystick to change to headless mode. The lights on the drone will change from 

permanently on to doing a double flash to indicate the drone is in headless mode. Push the left-hand joystick in 

again to return normal operating mode. 

To re-calibrate headless mode. After pairing with the drone pointing away from you move both joysticks to the 

lower right position and push in the left-hand joystick. The controller will beep twice and the lights on the drone 

will change from permanently on to doing a double flash to indicate the drone is in headless mode. 

Note: when the headless mode is calibrated the drone remembers the direction it was pointing in at that time i.e. 

the compass heading. That direction will be forward for the drone and all other directions will be relative to that 

direction i.e. back will be in the opposite direction irrespective of which way the drone is pointing or where the 

operator and controller are. 

Flips and Rolls 

You can enjoy some thrilling action doing flips and rolls. Click the Flip/Roll button on the upper right corner of the 

controller, the controller will beep to tell you it is in flip/roll mode. Push the right-hand joystick in any direction to 

make it roll or flip. Click the Flip/Roll button to return to conventional flight mode, the controller stops beeping to 

indicate no longer in flip/roll mode. 

One Key Return 

Push in on the right-hand joystick for one key return. The drone will return in the opposite direction to which it was 
pointing when it was paired.
