請問各位前輩，求教 DF-03 齒輪的作用和理論。

I still love the idea of ball diff, so easy to adjust, just right the bolt.......

Oil diff... Need to change oil, or the whole diff for adjustment, (better hv spare to race) and a bit too messy ....

However, it is true with the brushless power... Ball diff is hard to handle...

( Opps... 2800 yen for limit slip....3800 yen for one way .... *_* )
