Does the SparkSwitch Pro support native sbus for the throttle signal? I see PWM signal to the receiver, but I figured I'd ask anyway, just in case. In the manual I see sbus2 is supported for telemetry for temp and rpm sensors, etc... But it also references channel 12 being used, not sure of the use of the channel. Lastly, in my current setup I'm using the RX batteries to power the ignition, does the SparkSwitch require a separate battery or can you power it from the RX battery system? Thank you in advance for your help.
