UCAN-DO 3D or the Goldberg Extreme 330, I have about 200 flights on the extreme and just aquired a 46 ucando and am getting used to it.
I am running a Tower Hobbies 75 on each with 12.25 x 3.75 APC props.
Each one does certain things better than the other, there are many many good 3D planes out there and set up on them makes all the difference in the world as how they fly along with wing loading.
