A traditionally shaped balloon with horizontal panel cut. A low number of gores with its particular bulbous shape was very characteristical for this type. The envelope was very flexible and more fuel efficient since the balloon, for a short term, exceeds its volume by every burn in the envelope.
The O Model was more of a colored balloon. It was difficult to place any advertisements on the envelope due to its shape. O Model was substituted by E Model.
