I just finally pulled my old brush out of my motor and put in the F-Brush.
All I have to say is HOLY ***** its fast as ********.
From the first punch. My car acts completely different. I have a slipper clutch and diff....and before I would punch it at a dead stop and it would slip for like 1-2 seconds...and it would kinda take a sec to get that slip at first.
Now its instant slip all the way till top end.
Its amazing. Its like a whole new motor , the thing drives completely different. Its like I either just bought a battery thats twice as good or a motor thats twice as fast but with the same relative rpm.
Before = WRRRRRZZZZZZZZZZEEEEEEEEEEEEEEEEEEEEEE
Now = WRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRRREEEEE EEEEEEEEEEEEEEEEEEEEEEEEE
Its amazing. Everyone and their grandma should get this. I bought a few of these and also came up with a neat trick for cleaning the comm. Now I dont have to worry about getting it lathed all the time.
Also my old brushes were completely flat? Is that better? Can I still use those. I think my sides were getting all weird and chunked off. I think I chucked them, but thats ok they were crappy compared to the F-brush. So how many runs or builds (if you can explain it) can these take?
