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 gear in the up and down positions.
    they DO NOT have any ways of end point modification and can not be
    adjusted by ATV on a transmitter. They are only able to go 180
    degrees and supply full maximum readily available torque at the 2 end
    points. This is their entire purpose and intentional style|style}, but if
    someone has a unique design situation where they need aside from
    180 degrees readily available, then they must use a proportional servo,
    not a retract servo. They are specifically created to withstand
    consistent 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 small servo is used to move the air valve back and forth
