remember to usualy the more force a servo has the more draw it has on the battery. probably 150oz steering and 75oz brake/throttle will be good for a buggy, add 50oz/ea for a truggy (bigger wheels, harder to turn and slow down). i have an ace 1013 in my buggy at 173oz and it is stronger than the servo saver, so over 300oz of steering doesn't make sense to me, unless you lock down the servo saver i guess. get the best servos you can afford cause if they go, your day is over, and don't be afraid to have some cheep spares too, maybe blue birds just in case.
