The Extra 300L is a two-place, low wing monoplane, the 300L has a low mounted wing. The secret of the strength and agility of the 300L lies in Extra's advanced design concept utilizing high strength, lightweight composite structures. The wing spar is made from a carbon fiber/epoxy material that assures a large safety margin even at 10 Gs. The skin of the aircraft is more than 90% composite allowing for a high gloss surface finish and a very low value for parasitic drag.

The cockpit has great visibility afforded by the huge bubble canopy along with an installed GPS receiver make VFR navigation an easy task.
