New Syma X8G suddenly flips over mid-flight. Thoughts?

[Scyma]

I got a new Syma X8G and took it out for its first flight and found that just a couple minutes into the flight it suddenly flipped over and crashed into the ground. I recalibrated (held joysticks to the bottom left and bottom right), and tried to fly again, but with the same results. I switched out one of the motors on the right side--the side it always seems to flip over toward and it didn't solve my problem. I just attempted another flight and sure enough, about two minutes in it suddenly flipped over and sped into the ground. Any thoughts on what could be causing this?

Edit: I have made certain the blades are correctly oriented. It will fly just fine for a minute or two before flipping.

Maybe the one button flip is somehow being triggered on your transmitter or acting erratically and just causing it to "half-flip" and zoom to the ground. Not sure how to correct this issue without getting a new transmitter.
