Just starting the coming version 5 topic.

The new version is a complete rendition of flight physics and user customization about to be released.
And as some of you may be happy to hear about as I am, they have released the chains on the model creation ability, allowing the import of completely custom CAD designs that surely will have the phoenix owners creating a plethora of design creations that will be free source for all to enjoy.
