If you were on a budget, or just didnt want to spend that kinda money on servo's, you could use the Futaba 9202 servos which are analog, a little slow, but has over 90 oz. torque, and they would work fine. However the Futaba 9202 servos still cost approx. $50 each, so its really not that much difference in price. I get my 9252 servo's for $75 each, and the 9204 for $80. Daz...
