"If your better because you can do 3D on a 25% how about if you can 3D on a small .40 sized plane like a Sig SE?"

Then your awesome!

No, actually, comparing the SE to a Scale plane is getting into an apples and oranges thing. The SE and other fun fly planes are easier to fly than a cap or extra model that is more or less scale.

I think you have to look at different sizes of just one type of plane for this comparison. For example, a .40 sized Extra or Cap is going to be VERY hard to 3d......even compared to a 25% Extra or Cap. I remember when I first went from a .40 size Extra to a 25%, I was like "WOW!" it was like a whole new world opened up.
