    Overall good servo, somewhat sloppy but resistant gears.
    Price is overestimated and should be lower for this size and quality.
    Used them in F5 400 class with some problems (one servo became jerky after circa 100 flights). Now have two of them in 1,5 m flying wing.

    Very nice servo, I use the Indoor model airplane.

    connector is not compatible with 2.4Ghz FHSS Compatible A-Micro 5CH Receiver (Hitec Minima compatible) has different dimensions (therefore the 4 stars)

    Great servo for it's price and weight.

    A lot better than the 2,5g jst servo both in resolution, power, speed and precision.

    So if you can handle the 0,8g more weight this is an excellent option for smaller planes.

    Using them in a 60cm scratchbuilt Yak55 weighing 83g rtf. Perfect for 3d where the 2,5g was not strong or precise enough

    The JST mini-connector wiring has not standardized yet, its up to you to verify the correct polarity.

    Changing red and black cables for operation with ar6300 was easy. A hobby knife is all you need.

    Despite reading about the wiring issues, I plugged them into my AR6300 without changing the wires around. Anyway, despite the strong smell of burning electronics they still perform quite well (after swapping the black and red wire around). However, the JST plugs are very difficult to extract and tugging on the wires is not an option as they tend to break or pull out from the plug. I also broke one of the gears recently during a landing.
