169.0. "mini servos not for all applications" by HPSCAD::WFIELD () Tue Jun 02 1987 13:50

    Are you using mini servos (similar to futaba s33) in your plane?
    If so you might want to consider using the standard size servo.
    I lost a .40 sized ship to a futaba s33. The servo has plenty of
    torque, but the gear train is kind of weak and lost a tooth on the
    elevator servo coming out of a dive (control surface flutter).
    Now I only use them in electrics and 1/2A stuff that really needs
    them. Has anybody else heard of similar problems with the mini
    servos?

169.1I need micro servosANKER::ANKERAnker Berg-SonneTue Jun 02 1987 14:0312
        Re:< Note 164.13 by HPSCAD::WFIELD >

                I got  the  mini  flight pack because of the mini servos.
        The aileron servo  has  to  be  mounted  into  a very shallow and
        narrow airfoil and the  plans  specify  micro servos.  I tested a
        regular size servo and it  clearly  was  much too big.  The other
        three  servos also need to be  small  because  they  are  mounted
        directly  above the aileron pushrods and can't  be  moved  a  lot
        because of the short length between bulkheads.   Hope I don't run
        into the problem you describe.
