G2 plane Editing?
Good question!
Most likely you could always make it fly like a Zagi 400X. The flight characteristics are based on the various data you enter in the "Edit" screens. I have found G2 to be very good at simulating flight characteristics accurately.
As a sidenote, I "built" a Sig Kavalier in G2 a few months ago. I have been flying a real Kavalier since the early 80's, and the simulated one in G2 was so close to the real thing it was almost scary. And the only credit I can take for that is for entering the data... it is G2 that does all the magic using what you input.
The problem would be what the model would look like in G2, as you cannot change the shape of the existing aircraft and you cannot add new shapes. This means, you can probably make your design fly like a Zagi, but it would have the shape of a PT40, AT-6, Skybolt, or whatever you would have based it on in G2.
This is pretty much the only detail which I don't like about G2. I would like to see at least some basic shape editing function, but I have absolutely no idea if that is coming in some future version or not. For many designs you can find an existing airplane that is close enough for looks, but for a Zagi 400X (a flying wing, isn't it or am I mixing it up with someother model?) is see your problem.
