I started out with a XA X650V8. Built it complete and tried to fly it and all 8 props that came with it failed at the center before I could even get it off the ground.
I finally put graupner props on it and then it wasn't very stable and seemed lethargic trying to fly it. So i converted it back to V4 and still had the same issues.
So after doing some research, I found many people saying that the electronics are no comparison to the stability that DJI has.
So I then changed out the electronics and was also required to change the ESC and Motors as the XA motors and esc's don't play well with NAZA.
It flies good, but I think one of my ESC's are discharging my batteries too fast.
I am in the process of replacing one of them as it is the only one that is HOT to the touch within seconds of powering up.
I'll keep you posted as to my outcome once I replace it. Also, below is the link to the parts I ordered for the replacements.
