Gidday again Bill, please disregard 3dmagic's rude reply to your advice. He has obviously put his mouth into gear before thinking it through. If Mazlat's other servos are running on 6 volts then why not throw in the diodes on the futubas power line? Regardless of, if it's right or wrong there is no reason for belittling a new member or senior for that matter. Regards, John from downunder.
