The DF Helicopters DF334 is a two-seat, single-engine light utility helicopter in development by DF Helicopters Srl in Northern Italy. The DF 334 is a development of the Dragon Fly 333, developed by archaeologists and filmmakers Angelo and Alfredo Castiglioni in the 1980s. The DF334 has a larger, full composite cabin, a Rotax 914 4-stroke turbocharged engine, a governor fuel control, and an advanced Electronic Flight Instrument System. The helicopter is intended for both amateur and professional pilots.
