Model battery voltage return can be easily achieved by connecting the male end of the battery wire to
ESC while the female end to the battery and the wire with a JST head connects Telemetry (+-) port of
R8FG/R7FG/R8F as below pic shown. No extra module is needed.

Attention:
1. Reverse polarity protection circuit design for all 8 channels of R8FG ensures vital components are
protected from a reverse polarity connection. But, the JST connector which is packed with R8FG for
connecting to the battery cannot reverse polarity connect, or it will lead to the wrong voltage value
telemetry.
2. Telemetry port is only used to model voltage telemetry. It can not be used to power the receiver.

3. Child ID

RC8X can bind with multiple receivers. When RC8X and multiple receivers have been bound successfully,
and RC8X and all successfully paired devices are turned on at the same time. There are two ways to use
them:
1. When Child ID function is turned off, RC8X can control multiple devices at the same time.
2. When Child ID function is turned on, RC8X can control the specified device according to the selected
Child ID. RC8X has 16 groups of Child ID functions, and each ID corresponds to a receiver. Set the Child
