A retract servo is a very specialized servo. It is non-proportional,
going 180°, "lock to lock". They are made specifically for
mechanical retracts to lock the gear in the up and down positions,
and DO NOT have any means of end point adjustment and cannot be
adjusted by ATV on a transmitter. They are only able to go 180°
and provide full maximum available torque at the two end points.
This is their whole purpose and intentional design. If someone has
a unique design situation where they need other than 180° available
they must use a proportional servo, not a retract servo. They are
specifically designed to withstand constant 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
standard or mini servo is used to move the air valve back and forth
