COMMENTS:
A retract servo is an extremely specialized servo. It is non-proportional,
    going 180 degrees, "lock to lock". They are specifically produced
    mechanical retracts to lock the equipment in the up and down positions.
    they DO NOT have any means of end point adjustment and can not be
    changed by ATV on a transmitter. They are just able to go 180
    degrees and offer full maximum available torque at the 2 end
    points. This is their entire purpose and intentional style|style}, but if
    someone has a unique design scenario where they need besides
    180 degrees available, then they must utilize a proportional servo,
    not a retract servo. They are specifically created to hold up against
    constant holding loads in the up and down positions, distinct to the
    usage of mechanical retracts.
    Pneumatic retracts do not need a retract servo. A proportional
    standard or small servo is utilized to move the air valve back and forth
