Does a .15 size 3D plane exist?
Not that I've heard of.
However, Joe at down on the deck rated the world models .30 extra as a good small 3D plane. He said it harriers and does most of the 3D stuff well. Suprising for its size given that it is not a funfly type of plane. I am thinking about getting this one just to see for myself. Quantum models has them for $129 I think.
