  • And another - dual motor control

    If I want to be able to control prop speed on a dual prop setup, do I use to ESCs on two channels or what? Is there an issue if there is a BEC on each channel?

    Setting up for winter projects....

    Thanks
    Chris

    You can run them on two separate channels but make sure to cut the red wire on one of the ESCs, on the 3-pin connector that goes to the receiver (not red the ESC power wire that connects the battery). The receiver only needs to get power from one ESC, not both.

      Don't cut the red wire... You might want to use that ESC for something else in the future... Disconnected by Carefully lifting the little clip on the black connector and pulling the wire out folding it back with a little heat shrink on it.

        The Throttle Jockey is designed specifically to do this. It takes throttle input and rudder input to control two motors.

          I forgot what the UDT guy's told me. Was it, 'cut the blue wire', or was it, 'cut the red wire'? Could never get that straight. Oh, well, not that it matters much.

                If you cut the wrong one, you’ll never know it.

                  So, does it reverse the inside prop or only slow it down? Online description is unclear.

                  Thanks

                    I think some of the newer brushed esc don't require it. Also, unless the sub is large or the motors are brushless, there is little value in it. You can put the motors in parallel on one esc.

                      The Jockey will adjust the throttle outputs in a turn as a function of throttle input and rudder. With throttle at neutral, full rudder will command a full forward on one side and full reverse on the other.
