* = Channels that can be used to control receiver outputs (all outputs can be associated with any channel)
WIRES and CONNECTORS:
A wired 'W' version is possible with 2 wires for power and 2 wires for the motor.
A vertical connector 'V' version is possible which also has a 9-way socket. 5 are for 'P' outputs, 1 is 4v for a small servo, and 3 are negative. The socket is a standard SIL 'turned pin' IC socket. It accepts the same as plugs or 0.5-0.6mm single strand bell wire.
