__NOTOC__ The Dragon Fly 333 is an ultralight utility helicopter developed by archaeologists and filmmakers Angelo and Alfredo Castiglioni in the 1980s. 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. ==Variants== * Dragon Fly 333 - initial version * Dragon Fly 333 AC - RAI-VLR certified version * CAC Systèmes Héliot - drone version 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Castiglioni Dragon Fly 333」の詳細全文を読む スポンサード リンク
