I need some suggestions.

I need some help in finding a servo that can rotate 360 degrees. Does Hitec or Futaba have any servos that can accomplish this? And I am wanting to find it in my hobby shop, so a specific type would be of great help.
I don't want to have to buy them online, because I am making a trip up to the hobby shop to get some servos for general applications and I thought that it would be a good idea to get this one aswell.
Thanks, Kurt.

Rotate 360 degrees or a continuous rotation servo?
If you want a continuous rotation servo the LHS probably won't have them, but one option is you can ask them to order it for you and in a week or so you can buy it from them when it arrives.

I guess that's a good idea, and the reason for the 360 degree stop is because I have a rotating platform, and if it kept rotating to get to the next "closest" position, it would create an issue. So now that I think about it... If you have a general suggestion (internet or not), of a place in which I could find one, that would be awesome.
Thanks Razor Concepts for giving a clarification on what I needed.

have you considered using an electrical stop?
eg something that makes contact to tell the mcu that is has reached 360 degrees rotation?

That has played out in my mind a bit but if I can find a servo with that spec in would be awesome.

yep, it would probably be more expensive, yes?

Use 2 servos, one horn hooked to the other, one servo upside down. Bottom servo does 0-180, top does the remaining 180 to 360.
Or get a sail winch servo, does 3.5 x 360

Or get a 360 rotation gearbox ;

Use a stepper motor. You can rotate any amount of degrees you want very accurately. A stepper can also move faster. The only disadvantages are the simplicity of driving the motor, power and size. Depending on your project though a stepper may be a better choice. If the load on the motor is small a stepper would likely be a better choice.

I doubt that you will find 360
o
servos in a general hobby shop, I'm not sure about how big this store is but I would doubt they would have anything but the usual 180
o
ones. I think you may have to go online for it.
If you want to modify a normal one to rotate 360
o
there is a tutorial
