I have said before and I still stand behind it. A good 3D plane would be a great first or second plane. I prefer the Morris Knife because you can beat the tar out of it. Mine has gone full speed into a drainage ditch in a take off and 50 feet straight down into a muddy field. It is still flying.
3D planes in general are sweethearts. All you have to do is get the throws nice and gentle and it will forgive you all the way to the deck. My second plane was a scratch built Gee Bee profile and it is still flying. The only drawback is it will teach habits that a normal plane won't tolerate BUT after owning a plane like this you probably wouldn't want a plane that like that.
