I got my extra 330L 50 size from nitroplanes.com. i have to tell you, that it is a very good looking airplane! I have not started the build yet. The first thing I notice was a .46 size engine would not be enough power to do 3D with this plane. As reported on all the other treads on CMP models, the instructions make no sense. But the quality of the plane is impressive. I haven't decided what engine to use. I was thinking OS 61 or The new Evolution .52. I will post a video of the plane as soon as I fly it![8D
