    Hello
    I ´ve found this circuit at http://electronicdesign.com/Articles/Index.cfm?AD=1&ArticleID=6235
    and need to modify the values to obtain
    the standard hobby pulses r/c, preferrably 0.5 ms to 2.5 ms pulse width
    @ 50hz.
    Note:For larger R values the designer of this circuit recommends D1-D4 change to 2N3904 in place of the 1N4148.
    Thanks for your help!
    ;)

    This should work as a servo tester.
