Without using the S.BUS output extension energy channel, RBDM has 8 PWM channels, R6DM has 6 PWM channels, and R4DM has 4 PWM channels to choose from.
When using the S.BUS output to expand the servo channel, R8DM outputs the S.BUS signal on channel 8, R6DM outputs the S.BUS signal on channel 6, R4DM outputs the S.BUS signal on channel 4, and the remaining channels still output normal PWM signals.
The delay is 13mS when connected to JR-XG7 remote control, and 14mS when connected to other models of remote control
