REVIEWS: A retract servo is a really specialized servo. It's non-proportional,
going 180 degrees, "lock to lock". They are particularly made for
mechanical retracts to secure kit into the down and up jobs.
and Don't have any way of end point modification and cannot be
adjusted by ATV on a transmitter. They have been only capable get 180
degrees and supply complete optimum available torque during the two end
points. This will be their entire purpose and intentional design, but if
someone has a unique design situation where they require other than
180 degrees available, they need to utilize a proportional servo, perhaps not a
retract servo. They truly are created specifically to withstand constant
holding lots in the down and up positions, unique towards use of
mechanical retracts.
Pneumatic retracts don't need a retract servo. A proportional
standard or mini servo is used to maneuver the atmosphere valve back and forth
