If you want to go with a profile there are several good ones out there. I don't think the Goldberg Ex-treme is the best one for 3D. The 47" Edge is the plane OMP recommends for a 3D trainer. Paul Swanson's Burrito is another great 3D trainer. If you want an ARF you should take a look at OMP, they have several. Extreme Flight has a profile Edge that I like, but I don't know if it is in stock right now.
