I am turning my son's slash on to a mt slash it runs with the titan 12 t and its power by a 2s lipo , what gearing should be the best for it ? Currently is running the stock. 90 spur 13 pinion .. (i believe)
Also i want to give the differential a more of a posi feel so it wont get stuck climbing of the dried creek as it does now. ..any imput on this?would 300k oil be too much?. Is there a sealed differential for it?
