    The VTS-0XXx from Vegakit is junk!! :evil: They're ripping off students with a local substandard servo.
    I have 13 good 'vibrators' out of the 15 bought servos (over the counter @ Gala, Mumbai).
    I endorse Allbits' advise , as i have done the same....a glorified gear motor for 800 bucks!! ....and they don't provide any specs/details of it.

    hey I finally got my hand on a oscilloscope i checked my signal

    when i give it a signal of about 4.5ms high in 20ms pwm

    it gives a rotation of somewat 100 degrees(its a 180 degree servo)

    which makes me feel that instead of 1-2ms high period it has a diff high period for position control

    ne idea??? of any such motors which have a diff pwm requirements

    ps: i applied same pwm to futabaa s 3001 it gives full 180 degree rotation
