Yes, the node hold is bad: in fact, I'm not sure it even uses PID at all. But they can probably fix it. Or you can learn to fly the darn thing yourself... I didn't learn to fly with attitude hold, I learned to fly by the stars! (Seriously, though, I'm not kidding. I did not understand the navball at all, and would spend a minute and a half just figuring out which way to burn to go in the right direction. Those were the days.)
