    Application(s):

    5-10 Oz. sport planes

    Comments:

    I have at least 30 of these in my planes and have purchased several hundred that I have sold to flying buddies. Never a reported failure. Good centering and durable. Just great servos for sport flying.

    Application(s):

    All my cheap foamies, and some really nice small electric RC models too!

    Comments:

    At first I was sceptical, but my confidence grew the more I used them. Loads of them being used at our club with very few failures. One failed in my Trex 450 :-( Hard to beat them for value for money.

    Foamie servos all around

    Comments:

    I've used a lot of these and have never had one fail. What more can you say? They're dirt cheap and work well.

    Application(s):

    As cyclic and tail servos in T-rex 450 clones.

    Comments:

    Excellent servo for the money! They are stong, fast, and cheap. One of things I like the most is that you can buy replacement gear sets so you can repair these servos.

    Application(s):

    Rudder & Elevator on small electic powered slow flying planes.

    Comments:

    Over the past four years I have been using 6 of these servos and have had 5 of them fail. They suddenly stop working, the motor in them develops "dead spots" on the brushes and commutator. If they put a better quality motor in them they would be an awesome servo. They have been used in a very undemanding application on planes mostly gliders that are slow flying. None have been crashed or abused, they just stop working. Very dissapointed in these servos.

    Application(s):

    Trex 450 clone (HK 450) (all channels)

    Comments:

    The price is unbeatable compared to A-brand servos. I've been using them extensively in a 450 size heli even for the tail ( with a 401 class gyro supporting analog servos). They have been absolutely rock solid so far.

    I tested the torque of this servo and reach 0,8Kg/cm and the speed seems not to be right too.
    Dissapointed

    small planes/wings

    Comments:

    You get what you pay for. Has some of them in use but after 2 died with dead electronics some died with a dead gears i just dropped them. But as long as they last they are a nice bang for the buck.

    Application(s):

    Foamy sport planes

    Comments:

    Actual weight is 10.6 grams or so. Lots of torque, plenty of speed, fully reliable. I don't know what is happening with these guys who claim these servos croak all the time; they are used all over the world in scratch-built foamy fliers under all kinds of conditions. I use them in everything from 250-500 grams, and in 400-450 helis as well. I've passed dozens of them on to people who have put them into everything you can think of. They work and work well. And for $3 or so you don't even need to think of rebuilding them; just replace 'em.

    3d foamies, 450 cyclic

    Comments:

    These servos are amazing for the money! They are blazing fast, and have plenty of torque for my applications... However, one of them has a centering problem... thus my 4 star rating... But if it didn't have centering issues, it would be a perfect servo!

    -Happy flying!

    Application(s):

    Throttle, Ailerons, Elevator, Rudder for all 4 of my 44" W/S scratchbuilt 25 size Combat Planes ( total weight 1.8kg - Dry )

    Comments:

    Fantastic servo best value around ..performance is great for a $3.00 servo, never had one fail in flight and they get a tough workout flying Combat...have only had 1 fail for no apparent reason ...out of a total of 22 in use...apart from those damaged in model crashes...no problem just chuck in the bin and replace with a new ones.

    It's said Coreless motor. I think It's not. But I'm still happy with it.
    Good quality servo with low price

    One of the servo arms broke on the first flight around the ring that screws into the servo and crashed my airplane.
