All C-hing here, I have a ABC Genetic M chassis, I just wondering should I put "頭直軸" or "頭單向" on the car? or leave standard ball diff?
Also can any C-hing explain what is an advantage to use 頭直軸 or 尾直軸 for touring racing?
Thank you very much for any of you can tell me about it!!
Really recommend you folks to go to Team X-ray site and download their "Set-up Book" and spend some time to read it through; it covers all your questions. I personally find it very useful for myself.
