I know that not many people run brushed stock motors any more but i had a question on a rollout. i am going to be running at a flat carpet track with a 132 foot runline, and i was wondering what a good starting rollout would be for a monster stock motor, a cobalt stock motor, and a epic x stock motor. thanks for all the help

Try 2.20 to 2.30 rollout, thats if you are running 1/10 pan car.

does the x motor and the cobalt have to be geared different than the monster?

X motor and a monster are about the same(I think), where as aCobalt would need .1 to .2 more on the rollout than a monster.
