[NSRCA-discussion] Hacker ESC programming

[Richard Strickland]

Keep in mind it's reading the WHOLE pack and NOT individual cells--so if you
are cutting off at 3, chances are at least 1 of your cells is lower than
that.  I would suggest NOT using a cutoff for a tell-tale and get to know
your batteries to where you have plenty of cushion--i.e.-- one pattern plus
X maneuvers and LAND.

  RE cutoff...

  3.0 is the lowest you should use.... only use it if you can't get through
the sequence using 3.2/cell.

  The higher your cutoff (if thats your indicator to land..) The longer
(more cycles) your batteries will survive.  thats the whole point of the
cutoff... prevent destroying batteries.

  Not that some of the higher C rated batteries are now recommending no
lower than 3.2 v/cell.  Read the info on your batteries.  Obey THAT.

    C50 14XL Comp and Comp controller, TP 5300 batteries, APC 20.5 X 14,
drawing 65 amps at full power

    Timing is 3 (that's where Andrew and Jason told me to set it)
    Acceleration is soft (only affects from dead start)
    Throttle curve is logarithmical with my radio (14MZ) set to -26 expo 2
(personal preference from experimenting)
    Don't remember where my cutoff is, I seem to recall 3 volts per cell but
I'm never anywhere near it anyway.

    Hope this helps

    Verne

      OK it's a little quiet and I really do not understand some of the
setting available in the Hacker ESC programmer.

      I have both the standard C50 14 XL and the comp version.  I assume
that these settings are similar for other ESC's as well.



      Timing:  0-5 recommended for Hacker but what is optimal and what does
changing it actually do J



      Acceleration:  What setting is everyone using?  Does this setting only
affect a start from being stopped, or at all times?



      Throttle curve:  Is anyone using expo or logarithmical?



      What cut off voltage is appropriate for our current draw?

      I assume most people would use slow down at the cut off voltage and
not instant stop.



      Thanks,

      Stuart
