The Dragon Fly 333 is an ultralight utility helicopter developed by archaeologists and filmmakers Angelo and Alfredo Castiglioni in the 1990s. French UAV manufacturer CAC Systèmes created a drone version named the Héliot for use in reconnaissance and as an aerial target, but the aircraft did not enter production.
DF Helicopters was acquired in 2010 by a Swiss Group, Avio International Group.
