REMARKS:
A retract servo is an extremely specialized servo. It is non-proportional,
    going 180 degrees, "lock to lock". They are particularly made for
    mechanical retracts to lock the equipment in the up and down positions.
    they DO NOT have any methods of end point adjustment and can not be
    adjusted by ATV on a transmitter. They are only able to go 180
    degrees and provide complete optimum available torque at the 2 end
    points. This is their whole purpose and intentional {design|style}, but if
    somebody has a unique design scenario where they require other than
    180 degrees available, then they must use a proportional servo,
    not a retract servo. They are particularly developed to hold up against
    consistent holding loads in the up and down positions, distinct to the
    use of mechanical withdraws.
    Pneumatic retracts do not require a retract servo. A proportional
    basic or small servo is utilized to move the air valve back and forth
