Height: 25mm (1.0") Speed: 0.5 sec/60°

REMARKS:
A retract servo is an extremely 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 ways of end point adjustment and can not be
    changed by ATV on a transmitter. They are just able to go 180
    degrees and supply full maximum available torque at the two end
    points. This is their whole function and deliberate {design|style}, but if
    somebody has a unique design situation where they require other than
    180 degrees available, then they should utilize a proportional servo,
    not a retract servo. They are specifically designed to withstand
    continuous holding loads in the up and down positions, distinct to the
    usage of mechanical retracts.
    Pneumatic retracts do not require a retract servo. A proportional
    standard or mini servo is utilized to move the air valve back and forth
