    Great and cheap mini servo

    posted by SamiVakkuri on 06/30/2013 Certified Owner

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

    Pros:
    Great and cheap mini servo which can be easily modified to 360 degree servo (by opening gearbox, and cutting drive gear plastic stoppers and drilling the potentiometer locking from gear). All 10 ordered works well.
    Cons:
    There is no information about turning radius, so FYI: it is only about 190 degrees.
