COMMENTS:
A retract servo is a really 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 methods of end point adjustment and can not be
    changed by ATV on a transmitter. They are just able to go 180
    degrees and provide complete maximum offered torque at the two end
    points. This is their whole purpose and intentional style|style}, but if
    someone has a unique design circumstance where they require besides
    180 degrees offered, then they should utilize a proportional servo,
    not a retract servo. They are specifically designed to hold up against
    consistent holding loads in the up and down positions, unique to the
    use of mechanical pulls back.
    Pneumatic retracts do not require a retract servo. A proportional
    standard or mini servo is utilized to move the air valve back and forth
