Products Description:  

 The EMAX ES9251 digital servo is super tiny, lightweight, and ideal for small RC planes. From the moment you open the box, you will feel the quality. These little servos have rock solid digital centering, and lots of torque. You will not find any comparable digital servo of this size for anywhere near this price. 

Features:

These are advertised as a 4.3g sized servo, but most of them I have weighed are around 4.8g with the wire and plug, but no control horn.
These come with about a 7" lead with the universal "S" type connector that fits most receivers, including Futaba, JR, GWS, Cirrus, Blue Bird, Blue Arrow, Corona, Berg, Spektrum, orange rx, and Hitec
These come with the standard X-arm, T-arm, dual arm, single arm, and mounting screws.
