The CEA-308 is a Brazilian sports aircraft designed by Paulo Iscold,[2] that beat four FAI World Records with pilot Gúnar Armin Halboth.[3]

Design and development

The CEA-308, is an aircraft composed of fiberglass and wood, covered by extruded polystyrene foam plates. The wing spar is made of freijó, manufactured in plywood. A 64 HP Rotax 532 engine was used for flight tests, and later a 100 HP Hirth engine was installed, enabling the aircraft to reach speeds of up to 400 km/h. After some time it was decided to replace the engine with a Jabiru, which is the one that remains in the aircraft to this day. It has a three-blade propeller, also built by Hirth.
