Futaba S136G Compact Retract Servo
so they will fit into a wing.
This servo can produce high-current draw from your batteries.
If using NiMH or Li-Po batteries, make sure they are capable
of delivering sufficient amps.
Two Ball Bearings
Nylon Gear Set
Travels 180° - full-lock to full-lock -- to hold your gear in
position securely. Not proportional. Perfect for mechanical
retract installation. (see COMMENTS)

A retract servo is a very specialized servo. It is non-proportional,
going 180°, "lock to lock". It is specifically made for Mechanical
Retracts to lock the gear in the up and down positions, and DOES
NOT have any means of end point adjustment and cannot be adjusted
by ATV on a transmitter. It is only able to go 180° and provide
full maximum available torque at the two end points.
This is its whole purpose and intentional design, but if someone
has a unique design situation where they need other than 180°
available, they must use a proportional servo, not a Retract Servo.
Retract Servos are designed to withstand constant holding loads
in the up and down positions, unique to the use of Mechanical
