New to the CRT.5 have some questions

[Snipin_Willy]

Okay, I need to replace the turn buckle end balls, does anyone have a link to the replacement part, or a better/upgrade for them? I attempted to use some end balls from my 1/10 nitro truck that never gets used any more but they are too big. A tower hobbies link would be great because I have to order some other stuff through them anyways.

Edit: also, an aluminum servo arm would also be nice.
