COMMENTS:
A retract servo is a really specialized servo. It is non-proportional,
    going 180 degrees, "lock to lock". They are specifically made for
    mechanical retracts to lock the equipment in the up and down positions.
    they DO NOT have any methods of end point modification and can not be
    changed by ATV on a transmitter. They are just able to go 180
    degrees and supply complete optimum readily available torque at the two end
    points. This is their whole purpose and deliberate style|style}, however if
    somebody has a unique design situation where they need besides
    180 degrees readily available, then they must use a proportional servo,
    not a retract servo. They are specifically developed to hold up against
    constant holding loads in the up and down positions, unique to the
    use of mechanical retracts.
    Pneumatic retracts do not need a retract servo. A proportional
    basic or small servo is utilized to move the air valve back and forth
