RE: looking for a good 40 size 3d plane
I second YNOT's suggestion -- get a profile -- and make it a Mojo.
They are the best 3D-capable planes I've ever flown and real *tough*. You won't believe the punishment these birds will take -- which is always a handy trait when you're pushing your own limits.
If you enjoy flying more than building, fixing or just standing back and admiring then a profile will give you a hell of a bang for your buck.
