<DIV><FONT face=Arial size=2>The 9411sa would be fine. Swapping the final
output gear from metal to nylon with save almost a 1/2 oz total for 3
servos.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Run an unregulated 5cell pack (~1oz more than
a 4cell pack) and you will have about 20% more torque and speed. Or, just
bump up the output on your voltage regulator to 6.3v if going that
route.</FONT></DIV>

<P align=left><SPAN lang=en-us><FONT face=Arial color=#000080 size=2>I’m
trying to figure out the amount of torque required for my elevator servo
(single, in a pull-pull system). I’m doing an electric Impact and trying
to save as much weight as I can. I’m considering either the DS8411SA or
the DS9411SA. Not sure if the 82 oz/in of the 9411 will be enough?
Savings of .7oz (every little bit helps) times 2 aileron and one elevator
servo makes it worth while.</FONT></SPAN></P>
<P align=left><SPAN lang=en-us><FONT face=Arial color=#000080 size=2>There
used to be a site on the net that showed a way to calculate the required
torque, however I can’t find it.</FONT></SPAN></P>
<P align=left><SPAN lang=en-us><FONT face=Arial color=#000080 size=2>Any first
hand experience or good theories welcome!</FONT></SPAN></P>
