brief conversation with Dean Pappas on this subject recently. Dean explained
that some folks have been advocates of programming the ESC to do some footwork
at various stages of battery use. He explained to me just how easy this is to
do physically. It seems a few have mentioned something similar in this thread.</span></font></p>

not that concerned about raising the voltage of the battery as I see this as a
somewhat clear violation of the FAI code. I am more concerned about what
and how the ESC is "programmed" . I would like for some one with the
electronic/software pedigree to explain to me how programming adjustable rates
of voltage potential and making these adjustments automatically, does not constitute
a programming violation within the rules as they exist today. </span></font></p>

the rules were written, we were clearly dealing with RADIO pre-programmed
sequences and the like, no gyros, etc. However I would argue that rate auto
adjustments that are definitely possible with the ESC's of today, also qualify
as a violation of said rules. Someone should sit down and think this
through...I could be convinced otherwise but it needs to be a good argument</span></font></p>
