Hello Doz,
Sorry for not answering before but I have been very busy those last days.
You are right, SimFonIA looks difficult. But it just looks, because in fact it is very easy )). We are preparing a quick start guide that explain how to make a rotation and a translation. If we carefully look at your Tank, there is only two rotation and a translation to fully animate it (with the exception of tracks that are more complex).
Can you send me the model? I'll make a video to explain the process
Cheers, Julien from SimFonIA_team
