立方直升机的这种配置让他可以像直升机一样盘旋，但在向前飞行时，主旋翼的转速可以将下来，让两侧的机翼提供升力，在此情况下，两台螺旋桨推进器就能发挥大作用了。
This means it can hover like a helicopter, but when flying forwards can reduce the speed of the main rotor and let the wings provide part of the lift. Its propellers give the extra oomph.
要降低噪音，最简单的方法是增大旋翼桨叶的夹角，也叫“节距”，或是降低转速。
The simplest way to dampen a helicopter's noise is to increase the Angle of the rotor's blades, also called the pitch, and slow them down.
旋翼和旋转大臂转速采用闭环精确控制。
The rotation speeds of rotor and whirling bcam are controlled accurately with a method of closed loop.
