The FS-i6X and FS-iA6B was bind well, you don't need to bind again when you receive it.
If it is not bound to other receiver operations, it is not necessary to insert the binding plug.

If you have IA10B receiver, you can use 10 channel.

Multi-channel Hopping Frequency --- This system bandwidth ranges from 2.408GHz to 2.475GHz. This is divided in 135 channels. Each transmitter hops between 16 channels (32 for Japanese and Korean version) in order to reduce interference from other transmitters. Compatible FLYSKY AFHDS 2A Receiver
Unique ID Recgnition System --- Each transmitter and receiver has it's own unique ID. Once the transmitter and receiver have been paired, they will only communicate with each other, preventing other systems accidentally connecting to or interfering with the systems operation.
Bidirectional communication --- capable of sending and receiving data, the transmitter can display the voltage value data of the receiver FS-iA6B. (The voltage value of the power battery requires the purchase of FS-CVT01 Voltage Collection Module for installation)
Omni-directional Gain Antenna --- The high efficiency Omni-directional high gain antenna cuts down on interference, while using less power and maintaining a strong reliable connection.
Low Power Consumption --- The system is built using highly sensitive low power consumption components, maintaining high receiver sensitivity, while consuming as little as one tenth the power of a standard FM system, dramatically extending battery life.
