Try to fly it from your hand, apply throttle, but dont let the quad go just yet.
Be careful with the prop tho. Feel which way the quad want to go, and if you hold it in your hand, you can feel which motor is vibrating more than the others.
I used this method when i try to tune the pid settings on my quad.
Hold the quad from the bottom frame so your arm wouldn't get in the prop way

Yeah, the props are small enough that they should not cause that bad of a problem, the motor hubs are probably un-balanced.

This is a more complete guide, but as you have a KK2.1.x I can give you an easier way (no unmounting the motors and you can do it in place), if you have a KK and a flash tool get Stevie's 1.8, if not then get the iphone app he mentions and mound your motor to something like he did in the guide. You will hook the motor DIRECTLY to the receiver's throttle channel (usually 3) with NO PROPS and spin it up, you then try adding tape to the different sections, it should take you about 8 minutes or less per motor AFTER you have it setup, once you balance one try the tape in the same section on the other motors, as manufacturing defects are often consistent.

Hey guys, i'm very sorry i didn't reply, had some personal problems...
Nevertheless i'm back and with good news. My quadcopter is now very stable and it's much more easy to control. I updated my FCB and balanced motors. Thank you all for help, really appreciate it :).

And i'm now thinking of building a FPV quad. And i also want to give it a try with acro naze32 FCB. Looks very easy to configure.
Thank you all again ;).
