This 42-pound machine is powered by 14S 10,000mAh LiPos (that’s four 7S 5000mAh packs!) turning a Leomotion L110/230 motor for a whopping 1150rpm. The fuselage and mechanics are from Helicoptertechnik Schwing and a turbine sound module provides that extra realism. Futaba radio gear and a Futaba GY750 gyro allow this scale beauty to perform beautiful rolls, loops, turns and autorotations. Thanks to F. DLC for taking and posting this great video on YouTube.
