Believe me, it wasn't an easy decision, however, the decision was made due to the nature of writing code for the plane. My abilities in computer programming only extend so far, and I'm afraid I can't write a lot of the code for V9 that is automatically simulated in V10. At this point, it just feels like a lot of backwards progress, because every time a break through in V10 happens, I have to go back to the V9 model and write a new line of non-functional code and waste hours trying to line it up properly. I'm truly sorry that the plane has become out of your reach, however V9 designing is just too difficult from a dev's standpoint when compared to V10. I'm really sorry, but as you said, this project's been going on for 2 years (wow) and I need to finish it sometime, and being V10 exclusive is the best for the community. I'm truly sorry. ~Michael Chang~
