The guidance system consisted of propellor in the nose.

制导系统包括螺旋桨的鼻子。

Example: to fly forward, the back-propellor has to turn faster.

例如：想要往前飞，后面的推进器必须转得更快。

The outer wings, tail and propellor have been removed from the aircraft.

这架飞机的外翼、机尾和螺旋桨已经被拆除了。

The speed of the propellor that opposes the desired direction is increased.

相对于想要飞行方向的那个推进器的速度得增加。

The picture above is actually rather accurate, apart from that worrying propellor.

以上图片，其实是相当准确的，除了从这一令人担忧的。
