COMMENTS:
A retract servo is an extremely 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 means of end point modification and can not be
    adjusted by ATV on a transmitter. They are just able to go 180
    degrees and supply complete maximum readily available torque at the 2 end
    points. This is their whole purpose and intentional {design|style}, however if
    someone has a unique design situation where they need other than
    180 degrees readily available, then they must utilize a proportional servo,
    not a retract servo. They are specifically developed to stand up to
    continuous 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
    basic or tiny servo is utilized to move the air valve back and forth
