Narrative:

Sanford tower had advised that their radar is inoperative and that we could depart VFR and retrieve our clearance in the air with orlando approach. Upon request we inquired what altitude was safe for myself and the captain to climb up to. We departed east and climbed to 6000 ft. Climbing through 4500 ft to 6000 ft. We called orlando approach for our IFR clearance and said she doesn't have our clearance yet and if we knew that we were in orlando class B at 6000 ft. She then advised us to descend to 4500 ft and wait to pick up clearance. We pick up clearance and then proceeded on our flight. To prevent: IFR charts should show airspace altitudes.
