Firebird's 2003 (successor for the Matrix) DHV 1-2 Grid has passed certification. The most interesting design feature of the glider is the circular shape of the air intakes on the wingtips, which has a "significant impact" on handling, glide, speed, performance and safety, according to the design team. This design feature came out after research and tests done with the aid of aircraft development industries. Finally, they concluded that "the most efficient for rammed air and an increase of pressure was with pure round intakes.
The Grid is intended for recreational pilots and those who want "fun without worries". According to its creators, it has a light, precise handling and reacts to every input given. "It will do the turn the way you want, steep, flat, precise", they say. It has a maximum speed of about 48k/h according to DHV test reports.
