<DIV><FONT size=2>Max output torque of a servo is a function of battery supplied
voltage, the motor in the servo and the gear ratio. </FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Changing the signal line frequency will not alter the servo
output torque.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Also.. max torque of a servo can sometimes be a GEAR TRAIN
limit. otherwise it would be impossible to strip a sevo gear in
flight. No change to the voltage supplied is going to alter the strength
of the gears in the servo.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>It may effectively increase the servo resolution and thus
sensitivity to being off center, but it will not increase its available
torque.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>It MAY have the servo circuit apply more power at a smaller
deviation from "demanded" position... But that is an effect of
resolution.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>So.. it may apply full torque available at half the deviation
from demanded position... (may be what you MEANT to say...)</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2>Note that using a dual-inverter "glitch buster" <A
href="http://www.uoguelph.ca/~antoon/gadgets/noiserx.htm">http://www.uoguelph.ca/~antoon/gadgets/noiserx.htm</A> (especially
with Futabe 127 DF RX's) will boost the signal line from the RX output
(appx 3.8 v for the Futaba 127 when using 4.8 v NiCd pack) to full RX pack
voltage. This can increase effective resolution. (especially with
long servo leads)</FONT></DIV>
<DIV><FONT size=2>The circuit is INTENDED to filter interference from long
leads... and it works. The side effect is almost as good as the intended
purpose.</FONT></DIV>
<DIV><FONT size=2></FONT> </DIV>
<DIV><FONT size=2> If you can find the chip to make the circuit... I'm
having trouble finding the DIP (.10 inch pin spacing) I got some .05 in pin
spacing chips... which are going to be harder than heck to solder into the
circuit, but should do the job.</FONT></DIV>

<DIV>The nice part about this is it gives the ability of any analog servo to
output twice its normal torque. </DIV>

class=q> I know that Castle took a long time to introduce them to the
market. The initial designs that they had right after taking over Berg were
not up to the standards they wanted. I'm really impressed with these and
can't wait to try one. I'll also test them in a small IC plane before having
confidence in a pattern plane. The people at Castle are top notch. It's also
good to see an electronic component actually made here in the US.
