Which plane would be better the G.P.Venus 40 or a G.P. U-Can-Do 46 and what would be the best motor for one of these planes and it will get a 2 stroke motor.

They are very different. What is your experience level and what kind of flying would you like to do?

I Have lots of expreince but im looking for a plane that does lots of aerobatics but yet still flies good at lower speeds

Aerobatic can mean several different things these days. What have you been flying? Do you know the difference between Pattern and 3D? The Venus is a pattern plane and the You Can Do is a 3D plane. Do you want to fly fast and slow (Venus), or slow and very slow (You Can Do)?

I've been flying a Hangar 9 Twist 40 which is a 3d plane but i just don't like the looks of it

Then to answer your original question, the You Can Do would be "better". It is closer to what you are probably looking for.
