I've had descent results with hitec 7955, 7950, 7940 and I still like ko rsx servos but they are very pricey. I just ordered some Savox hv 1268 servos. With 361 oz of torque and at .11 speed I'm going the use them on both throttle and steering. I don't think the speed servos that move at .06 are quite built for the abuse of 1/8 scale. I just wish the servo companies could settle on the same size servo horn.
