will this 18NM servo motor work for 6DOF?

    Hi, i am looking at the following motors to build a 6DOF small rig.
    while these motors are smaller than the larger one, i'm hoping they are ok for a 6DOF and will fit well.

    the Servo motors are rated at 18NM with a peak of 55NM
    based on my research at 18NM these motors should lift a combined weight with a 3in arm of 318lb,
    at peak 55NM which is 486.9 lb

    if i reduce my lever arm to 2.5 in for a full motion 5 in, my calculations are at 55NM/1168LB or 18NM/832lb

    will this work for a home 6DOF, i don't want to throw you around to much, just have some feel to my flight sims along with the G-seat i already have installed.

    Specifically what 18NM Servo motors are you talking about, link, full specs?

    And what control board do you plan to use with them?

    this is what i know right now:

    - the motor is a servo based motor that runs on PWM so it connects to a arduino or something similar.
    - Servo speed is .16s/60 deg
    - servo angle is 0-360 deg
    - Rated torque 18NM
    -Max Torque 55NM
    - Max current 22A
    - voltage range max 24V
    -Precision .32 deg
