COMMENTS:
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 gear 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 offer complete optimum offered torque at the two end
    points. This is their entire function and intentional {design|style}, however if
    somebody has a unique design circumstance where they need besides
    180 degrees offered, then they should utilize a proportional servo,
    not a retract servo. They are specifically developed to endure
    continuous holding loads in the up and down positions, unique to the
    use of mechanical retracts.
    Pneumatic retracts do not need a retract servo. A proportional
    basic or small servo is utilized to move the air valve back and forth
