Thanks Matt
Actually their is no new editor. Its the same editor as always, you just model you new plane and then export it as a "KEX" file. All the parts of the model have to be named properly, moving parts have the correct axis and proper linking hierarchy (so the ailerons know to break off with wing etc). Next fire up G3 and you simply import the new plane just like you import a new Photofield. G3 automatically gives the new model basic flight characteristics, a collision model and it flies immediately after you import it w/no tweaking. At this point you can start tweaking the new model w/the editor or just change the .plng3 file to a model that is similar. For the Extra330S I started with the .plng3 for G3's Extra330s (add-on) and then did a little tweaking because my Extra is 40% size model. After you are satisfied with the results G3 creates a "G3X" file which is the finished new plane that can be shared with other G3 users. Of course you can still tweak the plane further and re-paint it etc.. just like any other plane in G3. Its that simple!
