Thanks Jeff,

And thanks for the info on Camera Position Controller. I'll have to see how that works in practice since I can't see how much it slows down the servo. Will you have any of your tanks using that system with you on the 23rd? I'd love to see it and how it all works. Since I'm not using a digital radio that could help, I'll have to come up with either some sort of slipper clutch or stops to keep the barrel from snapping off if it goes too far. I'd rather not use that pot if I don't have to even though it gives me the speed I'm looking for.

I appreciate all the help and advice as I'm just stumbling my way through this one piece at a time! =)

Dave
