increase Urban ops performance

​This is the photo I received from the netizen: Qiu Hao cheng, which has improved a lot of performance. The more obvious ways to improve it are shared with you: replace from Slicon grease to Slicon Oil, remember to completely remove the grease when replacing.

Silicon grease
Advantages: Can be used for a longer period of time
Disadvantages: greater resistance

Silicon Oil
Advantages: low resistance and fast speed
Disadvantages: need to be added often

這是我從網友邱大那邊收到的照片,提升了不少效能,其中比較明顯的提升方式與大家分享一下:
從矽脂更換成矽油,記得更換的時候要完全清除掉矽脂.

矽脂
優點: 可以使用較長的時間 
缺點: 阻力較大

矽油
優點: 阻力小,速度快
​缺點: 需要常常添加
