SERVO-Y-6 Common Sense RC Servo Y-Adapter, 6". This servo "Y" adapter is truly universal, with a JR/Universal connector on the receiver end and a Futaba J connector on the servo end.
 This means that you can plug any servo into the "Y" adapter, and plug the adapter into any receiver. These adapters are great when you need to run two servos to a single port on your receiver.
