The first 1写这么多, 喝口水~ for beginners, we should first have to learn to use the rudder, press Q or W will be able to maintain a high level of aircraft to the left or right yaw, steering angle deviation but this can only be suitable for large-scale is too small, so there is posts mentioned that the first arrival of a red circle must be straight ahead of the volume of the fly can not enter the brain to come to a large S-line, turn right at the first turn left circle off a No. 1, followed by the first 2, and then a quick switch to turn right over 3, 4, and repeat method is relatively simple, only need more practice to master a few lines on the OK, the operation from top to bottom and the only key QWE.
累呀~~~~头1次写这么多，喝口水~初学者，首先要就要学会方向舵的使用，按住Q或W飞机就能保持高度水平向左或右偏航，但是这种偏航转向角度太小只能适合大范围，所以，有帖子提过，到达第1个红圈前，必须要有提前量不能直直的飞入，脑中要浮现出一个大的S型路线先右转在左转过1第1圈，接着过第2个，再迅速转右转过3，4个，重复，方法比较简单，只需要多练几次掌握线路就OK，操作只需要上下和QWE键。
