REMARKS:
A retract servo is a very 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
    changed by ATV on a transmitter. They are just able to go 180
    degrees and offer complete maximum offered torque at the two end
    points. This is their entire purpose and deliberate {design|style}, however if
    somebody has a unique design circumstance where they need besides
    180 degrees offered, then they need to use a proportional servo,
    not a retract servo. They are specifically created to hold up against
    continuous holding loads in the up and down positions, unique to the
    usage of mechanical pulls back.
    Pneumatic retracts do not need a retract servo. A proportional
    basic or small servo is used to move the air valve back and forth
