Thanks for all your replies!! Your help is very appreciated.
I would definitively go with the Naza but someone mentioned above that I won't be able to do aerobatics. And I really want to try some when I get used to control my quad. Do you guys think I'd be able to make loops with AQ50D?
Naza all the way if you ask me, unless you're going to do aerobatics.
Are you sure I won't be able to do aerobatics with Naza? If so, it might be a deal breaker...
