Getting the flight controller near the balance point is the most important thing but it's also good to try to get the frame to balance close to the mid point between the front motors and rear motors. It doesn't have to be perfect. I have a DJI Naza M Lite and the GUI will compensate for an offset of the CG. The Deadcat can give you fits depending on which flight controller you use. A symmetric frame is much easier to set up but I really like the aggressive look of the Deadcat. I'll post a video later today of mine flying. It's been a while and I've made some changes. A lot of people try to put the FC in the middle of that "X" and the intersection of the lines is way to far forward and they fly really squirrely. Put the FC back near where the rear arms bolt on and it's a much tamer bird.
