I have the exact same frame motors. Make sure you have thoroughly read the Arducopter tuning thread for ideas but I manually tuned my way to:P=.140, I=.010, D=.006.
Following the guide and emphasizing getting D correct I wound up at P=.166, I=.010, D=.014, the "I" is not tuned I just threw it back in so it was not 0.
The wobbles are in fact a sign of P being too high and mine flew the same way out of the box. If you are getting weird flips, check your board mounting. I used the small plastic case and velcroed it solidly down. The velcro damps out a lot of vibration but holds the unit steady. The velcro acts like a low pass filter.
BTW, I edit my values in the table view rather than scrolling up and down in the menu view.
Hi Juan,
I'll help you get this tuned. I'll need the flash log of that flight. It will tell me everything I need to know to get it going.
You can download the flash logs from the planner or by using Arduino serial window.
Then just post them here.

As I recall, because that's a smaller frame you need to turn down the Rate_Roll_P value by about 20%. Not sure, but play around with that parameter. Up, down, you should be able to see the difference pretty easily.
