Gabriel,
Hey man can you elaborate about your DMM servos, how did you find them
as far as tuning and hooking them up, do you have any pictures of them
installed and what kind of machine are they installed on? Nice to hear
some actual good feedback about them, are these the 130mm sized motors?
Thanks for sharing and Merry Christmas...peace
Pete
