well, unfortunately you cant make the turbines spinning for human player. Asked chizh about em, and he said that only AI plaes can have spinning anims.
Tried to make them for the f-15, but they didnt turn out right. Think im gonna give up on them until someone finds a solution. And i dont think that you can make gun animation.
EDIT: just took a look a the model, and like WOW, my f-15 looks cheap compared to this, and correction: it has 114685 Polys ;)
