I have a mamba-25 ESC from castle creations and was wondering how I find the control pulses needed for full forward, reverse, brake, and nuetral. I have been doing seraches for control pulse for RC ESC but to no avail. Can anyone point me to the right direction, or give me some insight on controlling these types of ESC with the BS2p.

Thanks in advane

    bboy8012,

    After reading the specs on this controller, it appears to work with a standard servo input (1-2ms pulses/20ms), but needs to be adjusted to work with any particular radio receiver.

    I suspect that you could use the BS2 PULSEOUT command to generate pulses of varying widths between 1 and 2ms every 20ms and see how the controller responds.

    Just a thought.

    It's not that difficult, I have been playing with that myself for motor test stand.

    You can do it with simple PULSOUT commands between 1 and 2 ms. (Minimum and maximum)

    If I'm not wrong the pulses should come every 20ms. (50Hz)

    I first tested it with a normal servo, to make sure its working OK before I hooked up the ESC (CC Phoenix 25)



    Good Luck,

    Could I get an example of this?
