F109, changing parts

chings, pls help :

1/. which alloy servo mount can fit F109, around what price ? I use standard size servo only, not low-profile. The original servo mount plastic is rubbish...   

2/. Is F103 spur gear + steel ball fit F109 ? I bought a Tamiya spur gear but cannot fit the original differential ball into it. What is the ball size of F103 ? The original spur gear plastic also very rubbish.

3/. Also, any suggestion for the battery post that mount the double deck, the original one is also damp rubbish plastic.

Anyway, plastic parts of F109 is rubbish. Need to change, thanks all ching's helping !!

1.可以考慮Tamiya (#54088) F103 Servo Mount(ALLOY).

2.無記錯要改用3MM珠,當用星星大減.

其實原裝大減已是XENON出品,換上F103RM-11 64Pitch POM Gear Ring會更加好.

3.MY SUGGESTION

改用兩條26mm金屬柱代替原裝膠件.

換電方法參考F104.

Thanks ching,

1/. I already change to POM gear ring because thr original ring size is NG. But the original spur gear still very easy to sweep (already changed two pcs), so I want to try other brand spur gear.

2/. The 26mm binding post looks good, is it Tamiya ? Or whart brand ?

3/. The wheel looks very beautiful, what brand and where to buy ??
