elevator servo torque

[Wayne Galligan]

elevator servo torqueThat servo would be plenty for the elevator.  Either would work fine.
I have used the 8411sa and 9411sa and 8417sa high speed.  All work just fine.

  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.

  There used to be a site on the net that showed a way to calculate the required torque, however I can't find it.

  Any first hand experience or good theories welcome!
