Truck, Oops. My second grade English teacher will never forgive me. Your right. It does read that way. The regulator is for the airborne pack. I'm still using the 4.8 to 6.0 volt receivers and servos. I am concerned about stressing them with a steady state 6.6 volts. It also keeps the current draw lower. I don't need anymore torque from my servos. I get enough as they are. Dan.
