would seem to me that analog servos would be legal, but digital servos would
not. Under no load conditions, the two servos (theoretically) track
equally (“dumb” voltage AND power consumed are the same for a given
amount of rotation). Under a loaded condition, both servos consume more
power, but, the analog servos lags behind (in the amount of rotation compared
to a static no load conditions). The digital servo, relative to the
analog servo, consumes a greater amount of power to maintain exact same of
rotation (as static no load), and this is accomplished by consuming greater
power without specific command from the TX or pilot. The servo is
reacting to a specific set of conditions…just as the ESCs currently do now
with regard to changes in timing at different RPMs and different loads. Just
as the ESC would do if functioning to maintain constant power output.<o:p></o:p></span></font></p>

Subject: Re: [NSRCA-discussion] Max volts<br>
<br>
What the guys are talking about is designing an ESC that compensates for
varying input voltages. To make a rule against something so obviously
good is crazy. It would be like prohibiting voltage regulators on our
airborne RC system packs. Or prohibiting the use of circuits that
compensate for temperature changes in our systems. I'm for simplifying
the rules and regs. The fewer the better. Define the size of the
plane and the maneuvers to be performed and anything you can do to make it fly
better is okay. We want liberty not equality.</span></font><font size=2
