<DIV><FONT face=Arial size=2>Oh yes, one other side note - </FONT></DIV>
<DIV><FONT face=Arial size=2>- I generally run unregulated 5 cell Nimh or Nicd,
or if using lipos for the RX, I set the voltage regulator to 6.3 volts.
The high voltage is not a problem for these servos (or any other pattern
suitable JR servos). So the output torque and speed both improve pretty
proportionately compared to a lower input voltage from a 4 cell pack or Vreg set
to 5.3, 5.6, etc.</FONT></DIV>

<DIV><FONT face=Arial size=2>Nylon has better wear properties and the
geartrains can be produced with tighter lash without risk of binding.
The only real reason I can see to use metal gears is to increase strength
without increasing volume - which is needed when these servos are used in
applications with high impact loads (big IMAC style stuff and some of the
glider stuff - mostly for "shock" at landing as I understand it).</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>The "sa" is the nylon gear version - actually, to
be accurate, all the servos I listed use a metal pinion on the motor, three
nylon intermediate gears, and the final output gear is metal (to reduce flex
in the output shaft). FWIW, depending on the servo, you can save 0.1+/-
oz changing the final output gear to nylon.</FONT></DIV>
