Aero-Works is the only U.S. importer. I have flown both of the planes and i prefered the ca over the edge for imac but for 3d it was the other way around. The CA's long tail make it do very good at percison and imac. It will also 3d very well but not as good as the edge. It also comes down to avalibility we arent making the edges any more so it will be pretty dificult to find one. But we do have the CA's in stock. So if it were me I would go with the CA but thats just my opinoun.
