    Servo

    posted by Linix on 09/15/2013 Certified Owner

    Involvement:General (knows how to use it) - Ownership:1 week to 1 month

    Pros:
    SmThis is a nice little servo for fun-, slow- and park-flyers. IT works perfectly with my Multiplex receivers. All 6 servo I bought have no jitter and work precise and fast. Cheap! Good power! Very good responses and pulse. Smooth moving.
    Cons:
    From shipping all the oil can move to one side. I recommend you re oil it. Nothing else at this price.

    Good for the price but don't expect precision

    Involvement:Expert (understands the inner workings) - Ownership:1 day to 1 week

    Pros:
    Cheap, for sure, and can be used in most of the cases where a simple and cheap servo is required.
    Cons:
    I'm not sure if it is just the unit I got or they all have this issue but it doesn't reach the full 180 degrees of rotation exp...

    Good for prototype and cheap

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    It is cheap and standard size. It good for prototyping and little home things. I used it for mounting this hexapod: http://www.thingiverse.com/thing:31569 They fit exactly in the support pieces. Similar servos are more expensive.
    Cons:
    End stop is not absolutly precise, axis should no be positioned at the end of carrier. Screw holes are not closed.

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    It's works really good. It's pretty small; nice for small arduino/do it yourself projects. It's color matches the colors in the circuit.
    Cons:
    No datasheet included but it can be downloaded in the internet easily. It's gear can most probably break because it's just har...

    It works.

    posted by drashiel on 11/28/2012 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:1 week to 1 month

    Pros:
    It works, movement seems smooth and servo is very light. Pinions are plastic build, I have no idea how many time past until it breaks. Torque is adequate (1,2Kg) to little aircrafts or small rc cars and is very light (9 grms). Have complete adapters and 3 s...
    Cons:
    At this price, you can find other alternatives at half price with similar quality.

    Cons:
    As any other servo in this size with plastic gears, the gear can break. So you just have to know what you want, what you need a...

    Pros:
    Small, lightweight, fast respones time. Works well with my reciever. Looks pretty nice as well.
    Cons:

    Great servo!

    posted by carlosgss on 12/06/2010 Certified Owner

    Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

    Pros:
    - Cheap! Buy 5 as the bulkrate makes it the same price as if you bought 4 - Clear lets you know if a gear is broken later on. - Blue is a classy color, but if you don't like it you can paint over it to make it whatever color you like. - Included control ...
    Cons:
    - Was very oily out of the bag - One of them had no grease inside the gears.
