雙星黑豬

請問師兄們,雙星黑豬有無機會會無炭刷的, 我用 雙星 的 101 電變, 玩 F1, 電是充滿的, 俾油時部車唔行, 用手推下個車轆時佢先郁. .. 仲要唔係快果隻. . 看過入摩打內裡, 炭刷應是足夠的....

I had similar case before with fan black pig. Most likely the commutator dirty. I use a tube to spray alcohal into the carbon brushes area a few times and let it dry, then use air spray unit to blow off any dirty stuff, and spray some oil bases contact cleaner. Then I can use the motor again. But be carefull la, when you use the motor after cleaning, it will have some smoke and burn smell for the first few minutes, haha...

thanks for sharing your experiece, I will try to clean the communtator.
