I can help, my other project got post-poned 'till summer, so send me some stuff you want scripted, I can make GUI's and I have made a couple mods and released 4 of them:
Kill command (earlier on, this one sucked)
Mute command
Different colored jets
Wrench command
I can't model but I can script, I could try my hand at making weapons and I might be able to make it so only the pilot can fly planes.
