REMARKS:
A retract servo is a really 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 methods of end point change and can not be
    adjusted by ATV on a transmitter. They are only able to go 180
    degrees and offer full optimum available torque at the 2 end
    points. This is their entire purpose and intentional {design|style}, but if
    somebody has a unique design situation where they require other than
    180 degrees available, then they must utilize a proportional servo,
    not a retract servo. They are specifically developed to hold up against
    continuous holding loads in the up and down positions, special to the
    usage of mechanical retracts.
    Pneumatic retracts do not require a retract servo. A proportional
    basic or mini servo is utilized to move the air valve back and forth
