    Application(s): 450 tail with ZYX S2 gyro

    Comments: Make sure to note that this and all 9257 clones are 4.8v. only. They will survive 5v. but burn soon at 6v.

    Application(s): Used this for the tail on a 450 size heli.

    Comments: While it worked, it did well. Unfortunately, it only lasted 8 flights then quit. Looks like several people have had the same issues. Wont be buying another one, and cannot recommend it.

    Application(s): Helicopter tail control

    Comments: The servo failed and stopped working. Prior to this happening it was working great. I read that they have soldering issues. I will open her up and check the wire connections.
