Options available included full cabin doors, flaperons, brakes, wheel pants and a custom-fitted trailer.〔 The original Freebird I has been replaced in the company line by the improved LiteSport Ultra. A new variant, the Freebird 103, using the same wing with a redesigned fuselage, was under development in 2009.〔 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「Freebird I」の詳細全文を読む スポンサード リンク
