Have a magic 3d and have flown a magic extra. Quite frankly the only simmilarity is the magic in the name. My magic 3d with a tt pro 46 and a macks pipe can do anything (knife edge sucks couples badly, but does it). The magic extra on the other hand will not float like the magic 3d. Plus to get a decent power to weight ratio on the magic extra you need to use a 60+ size motor. All in all get the magic 3d youll be very happy. One word of caution the magic 3d is built from twigs, so be gentle. I also suggest chopping the wing tips off, I did this after my 3d flight and havent looked back. You can see pics of it on my site.
