    Any use. suits all uses.

    Comments:

    Good centering. Very strong and lightweight for a metal gear servo. This servo is an ultra low cost servo and can be sued in many situations :

    - As a gear servo on mini car 1/18, 1/16GP etc..
    - Rudder, Yaw, ailerons servos as it is enough fast to perform such abilities.
    - Mecanical for mini retracts on less than 500 grams planes.
    - Mini robots.

    It's a very cheap servo, and for the price, there will be no deception for low cost project.

    450 electric T-rex clone.

    Comments:

    I don't want to use these for anything that flies. All four in my copter lock up, if occurs some twisting that pushes axle inwards the servo. I might have "monday individuals", as usually I have read good reviews about these, but if you already have one of these, do a following test: manually rotate servo arm. It should rotate gently. Then apply very tiny pressure like pushing the axle into the servo and then try to twist. Those of mine are completely locked in place, until I pull the axle. I don't want my servos lock in place in the air!

    Comments:

    4 Helis and 2 planes were built using these servos and they all still work very well after many flights. I use the MG90S
    version. All center well and no slop...will continue to use them.

    Application(s):

    DO NOT follow #2 reviewer's advice on manually rotating the servo arm, it is not recommended (fact), period. used as aileron servo('s), rudder and elevator on small to medium 3d-foamies.

    Comments:

    out of 30 or so bought, maybe 3 bad. (out of the box) some were noisier than others. at $7.00 or less online they're a good deal. (opinion)
    my experience: stayed at a holiday inn one time

    Application(s):

    450 heli swashplate

    Comments:

    Maybe a bit too large for a "dressed" DS450 V2 but really strong and precise! I use them as swash servos driven by a 3X1000 3 axis in an Ecureuil semiscale, rigid triblade head...well: fantastic! No drifts, no shakes, the machine stands in the air like a rock in the ground! Much better then Align DS510 on my CX500 FBL where the 3X1000 was previously mounted.

    Trex 450 Pro

    Comments:

    Tabs broke off on all three servos during install and or reinstall setup. The case tabs are very very weak. Poor quality! Only tried to snug them up so they would hold and let the thread lock hold the screw.
