Eiswolf, you should just try.
Even if your models aren't the best, if you're working on something and have something to show, it'd attract more (positive) attention than just asking for help (which, IMO, just sounds fishy/ridiculous to expect anyone to respond to at all). You should be able to put together a few basic-looking models in Wings3D or some other free/easy-to-use modelling program to help generate some interest.
Even if you really can't, at the very least start a thread explaining what you want the goals of this "Aerotech Mod" is going to be, what direction it's going to go, check interest, etc. before just basically demanding help. Post a few screenshots/sketchs as concept art, talk about flight models/gameplay/weapons, whatnot! Get some hype going and people will volunteer to help without you asking...(or at least that's the hope), either way, it certainly wouldn't hurt your cause to let people know what is it that you're doing, because I personally have no idea what you're talking about.
Alright, I guess I should have said all of this first before doing my stupid sarcastic fairy comment...
