Making an arrow spin around a circle

Hi guys I’m working on a logo intro. Now the logo has a circle in between and there’s an arrow swirling all around it. I wanna ask how do I animate that arrow swirling? I mean I tried making a path around the circle and the making my arrow model follow the path but that was kind of weird, moreover that animation started from frame 1, I want it to start from frame 300. I’m sorry I’m in a bit of hurry while posting this, if U wanna see the logo its right here on my team’s (oh did I mention its my team?) facebook page, so please go check out the logo and drop a like too if u want… :stuck_out_tongue:

Any and all help is greatly appreciated…
