No problem Pete, just razzing you back!
Nothing came up on Google and I just could not get through to Horizon and trying to get my day job done in the meantime. Yes, 4031 is all I came up with also. I hate to ASSume (I like that) that the servo will work on 6v. It is going into a Sig 1/3 scale Spacewalker with a Saito 300, and the servo just happens to be on the throttle, so I would hate to smoke that servo during a flight. Thanks again.
