This is a replacement servo for those used on our Night Flyers, and works great on any foamy or small electric plane in the same weight class.  It has proven to be quite a bit better than the SG-90 servos we used previously, this servo is smoother, quicker, easier to move, and harder to strip than the SG-90.  We've sold hundreds of these and have had no problems whatsoever.  We also sell a metal-gear version of this servo for heavier planes.
 
Comes with servo horns and mounting screws.
 
Note: Color of the case may vary from smoke to blue, but the servos are the same.
