Here is the side view of the Movie Jetfire. This is mostly to show how the wings and feet would look. I added a backpack not only to house the tail fins, but also to better complete the Retro look I'm going for.

To the right, you'll notice a rough sequence of Jetfire changing from aircraft to robot with letters indicating where the parts go during and after the transformation.

And I did screw up the lower legs. I have a hard time mirroring drawings when they're so big and on seperate sheets of paper. I also just copied the head from the first drawing as just stated.
