I am not trying to bash Redcat with these vids......... I may have got a bad batch of diff cases and that is what caused the probs........  After shimming I had no problems and others with these have had problems and some not..... Some people on line had asked what I did  and I posted it............Plus I like tinkering with these things cause I like building and working and racing full size cars but with the economy what it is I had to find a cheaper hobby for the time being.
