I am familiar with the convention 180 degree servo where you can tell it
Code:
servo.write(86);
and it will move to 86 degrees but is there a similar servo motor out there that can do that but with the capability of 360 degrees? I know that most 360 degree servo motors have a calibrated stop position and if the given angle to go to is 92 degrees and the center position is 90 degrees then it will turn slowly and never stop. I am looking for a motor that will stop at 92 degrees and will hold that position the same way that a normal 180 servo does. Does anybody know where I could find one?

Yes there are a few available models. But there is sure a lot of confusion and misleading product descriptions when dealing with "360 degree servos" and "modified ex-servos" that are in fact continuous rotation bidirectional geared motor drives that can not longer be commanded to a specific position and stopped there.

This one is still a 'true servo' that can be positioned anywhere in it's 360 degree travel range.

i don't think they exist- i need some though!   smiley-money you could find a 2:1 (or 1:2?) gearbox, though, and modify it to fit a servo if it doesn't already.

While few, they do exist, often called sail wench servos.

Just in case you end up with some unexpected Google results, that's "winch".

Also the Mindstorms Lego motor works like this where you can specify a rotation angle.
