It is fully 3D capable, in fact it is the best damn 40-sized harriering plane I have flown (very stable once stalled). Waterfalls and walls are out of this world. Best blenders I've seen. But, rolling harriers will be snappy and hovering is not very easy due to the short coupling.

I have made some modifications to it that help a lot get rid of the snappiness many people complain about. It has to do with elevator linkage play. Have a look at this old thread:

I would suggest a 70 4stroke if you want max performance form the plane. The 46 might be a bit anaemic...
