JR DS8700G RC Helicopter High Speed Coreless Tail Servo. This servo has been previously mounted and flown. There are no issues with it. Servos operates smoothly and has only minimum play is the gears. Please see the photos for the details on this servo. If you have any questions, please send me a message. This servo has some gear noise but I'm not sure if thats normal or not. I'm discounting this servo in case additional work is needed on it. I'm selling it as is.
