Depends on the board, what I mean is I think there was a difference between my non-S&S (TK-01) and my RX14's. One gave 4-5v, one gave full available power (up to 7.2v).
Definitely works though, I have this mechanism in my [link=http://members.iinet.net.au/~wackywheelz/tanks/hobbyhavoc/halftrack/Dsc03164.jpg]
