supervision, to avoid the risks caused by beginners in the learning process.The trainer function can be enabled by 

selecting Status: ON. Then, users can set a switch to control the trainer function. When the switch is on, the trainer 

controls the aircraft. When the switch is off, the student controls the aircraft. For example, if the trainer and the 

student use two FS-ST8 transmitters for teaching and training. The trainer's FS-ST8 transmitter needs to be set to 

ON for this function with a control switch, and the student's transmitter does not need to be set. 

The transmitter provides four stick mode, you can set it according to your habit. CH1 represents Aileron, CH2 

represents Elevator, CH3 represents Throttle, CH4 represents Rudder.

2/4 (M2/M4)and modes 1/3 (M1/M3)will necessitate changing 

the throttle gimbals position. You need have to open up the
