I'd start with a different battery. If you can measure the volts when the motor is running you might find it drops a lot on one of your batteries. It should drop less than 0.2V per cell when hovering. When batteries start going this voltage drop can be much greater. You can only eliminate things one by one though by proving that things work. I use a lipo alarm to warn if the batteries go below 3.6V.
