I have to agree with everyone here that foam is the quickest way, and when you crash it is definatly cheaper. But I personally like the feel of a balsa plane (no flexing), plus I'm not an electric person. I would much rather have a gas plane than electric. I have a hanger 9 twist that's great for beginning in 3D. I wouldn't get the PNP version though, the servos are slow and I'm not a big fan of evolution engines. The only problem with the twist is that it's not a very smooth flyer. If you want a smooth 3D plane be sure to check out some YAK's.

Also, you didn't mention what size your looking for, or arent' you sure?
