With the helicopter hovering nose - right , add right cyclic and flip the helicopter to an inverted nose - right hover , hold for five ( 5 ) seconds 机头朝右保持停悬，将副翼打右舵使直升机翻滚为机头朝右的倒飞停悬姿态，保持静止倒飞停悬5秒钟。
From this inverted nose - right hover , add right cyclic and flip the helicopter back to an upright nose - right hover , hold for five ( 5 ) seconds 由机头朝右的倒飞停悬，将副翼打右舵使直升机翻滚为机头朝右的正立停悬姿态，保持静止停悬5秒钟。
This area is now bent slightly outwards , with reinforcement along the bend to restrict the flexibility of the endplate and the flap under high loads 这一区域现在被稍微向外弯曲，并沿着弯曲部分进行了强化，以限制端板和副翼在高负载下的弹性。
With the helicopter hovering nose - in , add left cyclic and flip the helicopter to inverted , continue until the helicopter has completed 2 rolls to the left 机头朝向操控者保持停悬，将副翼打左舵使直升机翻滚为倒飞的姿态，持续地将副翼打左舵使直升机向左完成侧滚二圈。
