Castiglioni Dragon Fly 333

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.
