This servo is designed especially for the GY601 and the GY611 gyros; it will not work with any other application.
The manufacturer claims that the S9251 is the only servo that can be used with the GY601 gyro because no other servo has a sufficient frame refresh rate.
The GY601 can only be used at 4.8 volts; higher voltages may damage the gyro.
Manufacturer Warning: "When mounting this servo in the fuselage, ensure that the servo case and the metal parts of the helicopter frame do not touch, to prevent radio noise."
Manufacturer Warning: "Immediately after flight, do not touch the S9251 case. The heat sink section of the case may be extremely hot, and may cause burns."
