I've never been able to get my pedes and rustys to stop shedding yokes, spurs, and diffs if I give it too much power. You might be ok for some careful speed runs if you take it easy, but before very long you will snap something in the drivetrain. Just make sure you are using as lite weight tires as possible and let that slipper whistle.
Not sure if you are interested but I have a 1600kv 60mm medusa for sale. 1600kv is a good rating for 6s a123. You will easily get 45mph out of it, could probably gear for 60!!!
