    Application(s): All around except throttle, OMP Yak

    Comments: First servos I ever bought, six plus years now, sent them in a year ago and they all checked out fine. Recently bought more to replace Hitecs, my 5245 jammed and crashed my plane, no more Hitec for me.

    Application(s): Seagull Edge 540, OS120, throttle servo

    Comments: I lost a nice Seagull edge 540 when the throttle servo
    gears jamed and it pulled the battery voltage down
    to 3.5v, causing the other servos to wander around
    aimlessly. I wouldn't recomend this servo on anything.
    I'm also switching to Hitec servos in the future.

    Application(s): Extra 330 68" span all EX rudder

    Comments: good nice servo for the price NEVER USE THREAD LOCK it kills the gears. good sports servo not doing 3D so no need for silly fast speeds. done 50 flights with them now with no problems and still tight..
