In the meantime I found out that there is no way to create your own flying model in Phoenix RC, you can change textures of existing ones, but that's it... There is no model 'modeler' so to speak ....
So, the batbone is not going to part of PhoenixRC soon unless they add it themselves...
No the only way to get a model in there is to follow their guide on how to take pictures of it, sent them in and hope they'll do the work for you =). Just wish the same went for flying sites, heh. I'll give it another go, too good to be skipped.
