    Comments:

    Used this servo on the tail of my 450 Pro Heli. Worked great for about two months and died in flight without warning. Running 4.8volts. I cannot recommend this servo. Beware!

    Tail rotor servo in an EXI 450.

    Comments:

    Performed perfectly up until the point where it mysteriously died for no reason. Was running at 6V, died after about 30 flights or so. Still powers up and holds center, but will not accept signal inputs.

    Trex 450 Tail Servo - used with Detrum GY48v Gyro

    Comments:

    I have this installed on 6 helis. On two so far I have experience failures, luckinly not in flight. Just like every said above, they work great and all of a sudden then start acting up and die. Nice package and nice looks but frankly for teh price (not cheap at $25!) they are not worth it.
