I was having huge traction roll issues last week. Turned out to be because I switched a used LiPo with no weights, so the car was too light, and that would also probably make it rear-heavy. So there just wasn't enough weight to keep the front end flat when entering corners and cranking the wheel (that's my n00b style, I enter hot and scrub speed by turning).
I'm curious if just moving weight forward would help with corner entry traction roll.
