In addition, I made some modifications to the combination. Jetfire's nose sits in the shoulders (they actually wedge in nicely) and are (still) detached from his forearms) I think the way they follow the shoulders is a lot more accurate. Looking at the art, he's got some big big toes/feet, so I added some magnetically attached feets on his feets. There are 2 small wings which flair out from behind his wheels on his lower legs, they also clip around and onto the sides... and 2 small wings from the sides of his chest.
Wait until you see his arsenal of weapons.....
