so i don't start a new thread i decided to revive my dead one...if i got the castle neu (2200kv/1515 1y) what would be a good gearing to make sure temps stay in check on 4s

EDIT: in a savage

i run a 18 tooth pinion on mine locked in second gear(3 speed) with the stock 47t spur i believe 47 is the stock but it is the stock for sure.
