[1]Since the FC has undergone an upgrade, these setting items are added later. If your FC does 
not have it, don't worry, it will not affect your flight performance. 

*When setting the AUX function, RC6-12 means the remote control 6-12 channel. 
*< FENCE RADIUS

>

 only works in fence mode, other modes do not have fence function. 

*After changing the <TELE>, you need to restart the FC. 
*After changing the <PORT>, you need to restart the FC. If it is set to AUX, the AUX3-6 setting 

items will be automatically added after restarting. 

 

Flight Summarize

GPS 

The FC supports UBLOX protocol, but does not support NMEA. After power-on, the FC 

will  automatically  configure  the  GPS.  If  the  FC  cannot  recognize  the  GPS  latitude  and 

longitude, you can reset the GPS through the setting item

 <GPS RESET>

How 

MAN 

The airplane is direct controled by RC. 

STAB 

Control the angle of airplane,and auto level when no RC input. 

ACRO 

Gyro mode,lock the current angle when no RC input. 

ALT 

Hold current height when no ELE input. 

FENCE 

Auto Retun Home when out of fence radius. 

RTH 

Auto Retun Home. 

* FENCE and RTH can only be used when the GPS is fixed, otherwise it will become the ALT.

 

 

Assisted Takeoff 

ALT/FENCE: 

Push the throttle to enough power, after takeoff(throw it away), the aircraft will 

climb to 20m automatically. 

 

 

RTH Mode: 

Push the throttle to enough power, shake the aircraft or run, then the motor starts 

slowly, and then take off after the power is enough(throw it away), the aircraft automatically 

climbs and circles over HOME. 

 

 

Throttle control 

MAN/STAB/ACRO/ALT: 

Throttle is direct controlled by RC.

 

FENCE: 

Before triggering RTH, the throttle is controlled by RC, after triggering, it is determined 

by RTH.

 

RTH: 

Throttle is controlled by RC during assisted takeoff, after entering the circling state, the 

throttle is controlled by the FC, it automatically adjusts the throttle according to the cruise 
speed you set, you can manually push the throttle up (beyond the throttle calculated by the 
FC) to increase cruise speed, but you can't pull it down.

 

 

Throttle differential 

When  an  AUX  port  is  set  to  throttle,  and  the  <THR-DIFF>  is  not  zero,  then  you  can 

control  the  differential  rotation  of  the  two  motors  by  YAW  channel.  It is  necessary  to  pay 
attention to whether the direction of the speed change of the two motors is correct, if it is
