The airplane comes with one-key U-turn function, which enable the plane to U-turn 

by the opposite direction that the plane 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.

NOTE: 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 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 flies the plane 

under manual control or gyro assist mode, when you 

turn on the one-key U-turn function, the plane will 

enter gyro assist mode automatically to help stable 

flying back. When you quit this function, the plane will back to the what the control 

mode it was.

NOTE: This function is bound to the receiver, instead of to the transmitter. That 

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.
