[NSRCA-discussion] Aileron servo arm size and resolution?

[Kelly Regan]

I forgot to add that I am running 6.0 volts with a
7.2 volt li-ion pack and Fromco regulator.

Fred, can you explain or give me an example of what you
mean by bad control system?

I have been trying to understand the affects of high atv's and resolution
for a long time and the information I find is conflicting.

At what point do you realize full resolution?  100% ATV and 100%
on the duel rate screen?   Is there an advantage in going to 130% ATV
as far as resolution is concerned?
