Important Warning

Do not connect a battery to the radio when in this mode. The battery voltage will flow directly into the controller and cause permanent damage if its voltage is higher than 5.5V.

This mode of operation is the most convenient and is the one wired in the R/C cable deliv- ered with the controller.

Connecting to a Separately Powered Radio

This wiring option must be used when the controller is used with a RC receiver that is powered by its own separate battery. The red wire in the loop must be cut so that the 5V out from the controller does not flow to the radio, and so that the battery that is connected
