The FS-i6S transmitter and FS-iA6B receiver constitute a 10 channel 2.4GHz AFHDS 2A digital proportional computerized RC System. This system supports quadcopters.
 
Touch screen
The AFHDS 2A (Automatic Frequency Hopping Digital System Second Generation) developed and patented by Flysky is specially developed for all radio control models. Offering superior protection against interference while maintaining lower power consumption and high reliable receiver sensitivity, Flysky's AFHDS technology is considered to be one of the leaders in the RC market today.
Features
Full touchscreen interface, more convenient to control
Bidirectional Communication Capable of sending and receiving data, each transmitter is capable of receiving data from temperature, altitude and many other types of sensors, servo calibration, and i-BUS Support.
 
Unique ID Recognition System Each transmitter and receiver has its own unique ID. Once the transmitter and receiver have been paired, they will only communicate with each other, preventing other systems from accidentally connecting to or interfering with the system's operation.
