[NSRCA-discussion] Hacker ESC programming

[Richard Strickland]

FMA has the Discharge Protection Modules that read individual cell voltages
but weigh about 3 oz. and at times have seemed to give some funky(seemingly
unreliable functioning) operation.  With the advent of fairly reliable
balancing, keeping track of energy use and heat, AND a high ESC setting for
'just in case'--that would seem to be the way to go as opposed to the DPMs.
There does NOT seem to be a one size fits all.  I've noticed some guys have
good results with one system and other guys don't.  Real strange...

Hi Richard,
That's exactly what I do. One time through Masters with no extra
maneuvers. That's why I wasn't real concerned about the cutoff. I never
get anywhere near it anyway. Of course, if a cell puffs in flight, it
would come into play, but the instant power reduction that causes tells
you everything you need to know anyway and a quick landing should
follow. Been there once and don't want to go back!
