Just rebuilt mine after running my Caster Racing all summer. i went a differernt route. I tossed in a 13.5 sensored motor and an 80 amp hobby wing esc. Running 3s lipo the thing is just as much nuts as it was on 4s and the 8th scale motors. I have retired my redcat due to diff issues. I now running the white associated grease in front and rear and the thicker black grease in the middle. My 3 year old is having a blast with it.
how bad were your diff issues?
my earthquake ran for about 10 packs before the rear diff failed. but when i tried to put a new one it i think the diff case didnt get tight enough cause the new diff failed in 2 packs.
But i think the buggy version should hold up better. Those massive earthquake tires (largest tires i have ever seen with a 12mm hex) put alot more stress on the drivetrain. So im hopefull that my diffs will hold up better.
Forget who on here has one, but he has a shredder and is running a 150amp system on 6s and hasnt had a diff go yet!
