You won't need special servos in any part of the airplane. Remember, the airplane was first flown when servos were rated at about 3-4 inch-pounds of torque, which is 48-64 ounce-inches of torque. Nosegear steering and rudder were almost aways controlled from the same servo. Only five servos were usually found inside those models: one each for ailerons, elevator, rudder/nosegear steering, throttle, and retracts. Some people would add a sixth servo for fine-tuning the needle valve.

You could use four S-148 servos or equivalent and do OK, but a midrange servo , such as the S3102 would be nearly ideal for most vintage Pattern models.
