How-To: Tic Tocs[钟摆][翻译进度100%]原帖: /showthread.php?t=248280By request...Prerequisites:You should at least be comfortable with forward and back flips. You don't really need to know how to fly inverted to learn tic tocs, but it certainly helps. The better you are at controlling any type of inverted flight or hover, the easier tic tocs will be.Tic tocs are deceptively simple looking. You'll find it's a lot more involved than just yanking the stick back and forth and jamming the throttle up and down. I'll show you how to break it down so you can learn how to control the collective stick seperately from the cyclic.Starting out:I'll talk about tail down/nose up tic tocs (aka elevator tic tocs) since most people will probably be most comfortable starting with these since the tail is mostly pointing in a direction you're familiar with.•Get to a comfortable altitude upright and tail in.•Give a little bit of positive collective•Pull back and do a half back flip until you are inverted nose in.•Give a little negative collective to catch the heli and hover inverted nose in.•Stay there for a moment and get the heli stableThen go back•Give a little bit of negative collective•Push forward and go back to upright tail in.•Give a little positive collective to catch the heli and hover upright tail in.•Pause again. Regain control, then repeat.While not exactly tic tocs, doing this will help you learn the coordination needed to control the collective independantly of the cyclic. At first try to keep all the collective movements seperate from the cyclic movements. You'll soon learn to apply collective based on what the heli is doing, not what the cyclic stick is doing. This is what we call "collective management"Keep doing this and your collective management will get better and better. Gradually start catching the heli earlier so that its more at an angle at each half instead of a full half flip.You can practice other orientations of tic tocs the same way (nose up, down, left or right). Just start upright and always flip or roll the heli towards you to inverted. Then flip or roll back.--------------That's the easy partNow comes control. In order to properly control your tic tocs you also need to learn to apply rudder and other cyclic movements at the same time you are doing the tic tocs themselves. Rudder movements allow you to move the tic toc left or right, and cyclic movements can rotate the heli to keep it on line.For example:If you applied some left rudder in a tail down tic toc the heli will start to drift to the left. Right rudder will steer the heli to the right. Also if you use some left or right aileron it will rotate the heli to the left or right which will allow you to keep the heli straight if it starts to rotate in an undesired direction (it will).If you are doing aileron tic tocs then rudder will still have the same effect, but now you'll need to use elevator up or down to keep the heli straight. What cyclic corrections you'll need during a tic toc will all depend on the heli's orientation. If all that sounds complicated it really is. There are actually 16 different basic orientations you can tic toc in. There's 4 heli orientaions:•Skids away (the standard tic toc orientation)•Skids towards•Skids left•Skids rightAnd each one of these has 4 basic nose orientations (up, down, left, and right) Getting profecient at all of them is likely years of work. Just stick with skids away to start.Trying to do tic tocs along with rudder corrections, and cyclic corrections all at the same time is extremely overwhelming at first, so when starting out try to just make tiny corrections on one side of the tic toc only at the slight pause in-between going from one side to the next. All I can say is practice this a lot, and eventually you'll learn to integrate the corrections you want in with the tic tocs themselves.Hope this helps. Work on the basic at first. Then worry about control later. Soon you'll be doing stationary tic tocs right off the deck.咋样做“钟摆”前提条件:你应该至少前后翻的很舒服，掌握倒飞对于学习“钟摆”其实可有可无，但掌握了倒飞悬停确实有好处。

倒飞各种航线掌握的越好，钟摆约容易。

“钟摆”看起来很简单，但是你会发现比单单的前后猛摇摇杆和油门复杂的多。

我会将“钟摆”分解开来让你了解如何将总螺距和循环螺距分别控制。

开始：我将介绍尾巴朝下头朝上的钟摆（也叫升降舵钟摆），因为尾巴的方向是和你熟悉的方向一致的，对于大部分人来说这样比较舒服。

1.进入时保持合适的高度，正飞、对尾。

2.加大一点正螺距3.拉起做一半后空翻，进入倒飞对头4.加大一点负螺距，控制住飞机，进入倒飞悬停5.稳定住飞机6.然后翻回去，加大负螺距7.推杆回到正飞对尾8.悬停，稳住飞机，重复练习。

上面练习虽然不是“钟摆”，但是能帮助你练习总螺距和循环螺距分别控制的协调性，这是“钟摆”必须的。
