RE: GP Venus fly 3D?
The venus is definitely NOT a 3D plane. It is very fast, and precise, more like a pattern ship. The surfaces are very small. I had one with a OS 46 in it, it ripped. It would not prop hang, but that is not what that plane is for.
Bad choice if you are thinking 3D anything.
The Ucandos are good for 3D but not anything else. The surfaces are so large and the wing so thick that there is no precision and if you don't manage throttly you will flutter.
Not sure what is good in that class. The UCD is a fun plane to fly.
