[NSRCA-discussion] Hacker ESC programming

[Earl Haury]

Same settings as Verne. 

I measured V / A / rpm @ each different timing setting on my test stand using the Eagle Tree data logger / sensors. At least with the C50-14 Comp motor (21x14 prop), I observed no significant difference in max A (+-1.5) / rpm (+-15) @ same volts (+-0.0) between several measurements with timing @ 0 - 3 - 5 in varied order. There could be temp differences (didn't measure), but likely small given A are similar. So - 3 deg timing seems a reasonable setting.

Logarithmical throttle response is much smoother than the others - especially noticeable with higher C batts.

  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
