| Three Ways to Improve Your CCPM Control 三种改进直升机CCPM控制的有效方法 |
| For extreme hard 3D pilots, every bit of force and speed in pitch control is appreciated and CCPM offers just that. The 120-degree CCPM is by far most popular among pilots of all levels. However, the minor interaction between fore/aft and collective motion caused by unequal arm length to the pivot line could be annoying. Here I would like to share three ways to improve it.
对极限3D飞行发烧模友来说，任何一点力量和速度对螺距控制都是珍贵的。CCPM十字盘控制提供了这些优势。在各层水平的飞手中，目前120度十字盘最为流行。可是由于到俯仰轴线力臂的不相等引起的俯仰和螺距相互影响有时很是令人烦恼。这里和大家分享三种改进的方法。

 | One quick way to solve this problem is to use fast digital servos to make the motion differential unperceivable. That is what I did with my TREX 600 Nitro Pro. Recently I changed to three JR DS8325 digital servos which made big difference comparing with my old JR811 servos.
最便捷的解决方法是使用高速数字舵机，把速度的差异降低到感觉不到的程度。我在我的亚拓600Nitro Pro上采取了此方法。我把原来的JR811舵机换成了JR DS8325，效果非常显著。

| | If you want to set up a perfect high end hard 3D machine, I would suggest use 140 degree CCPM which offers equal arm distance to the pivot line, giving you absolute zero interaction. I did 140 CCPM with my JR Vibe 90 3D together with three Futaba 9255 servos. It feels great. The only drawback is that not all radios support 140 CCPM.
如果你想追求完美的高端极限3D效果，我建议不妨采用140度十字盘CCPM设置。这种设置提供了等距离力臂，可以给你绝对的零差异。我在JR VIBE 90 3D上使用了140度CCPM，配上三个Futaba 9255舵机，手感非常好。唯一的不足是并不是所有遥控器都支持140度CCPM。

如果你想在不投资新遥控器的同时又能享受140度CCPM十字盘，你可以用120度CCPM的设置，结合使用俯仰和升降混控模式，把混控比调到35%左右。这种夸张的十字盘俯仰混控可以达到和140度CCPM遥控设备同样的效果。
With one of the above three trick, enjoy your perfect flight and have fun collectively!
以上任何一种方式都很有效。现在，你可以享受完美的飞翔和动作谐调的快感了！
