A vocal, influential, and hardworking modelaircraft enthusiast, Walt Schroder succeeded Bill Winter as editor. He held that position from 1960 until 1970, when he moved up to become the president and publisher of Air Age (its parent company). While Walt was editor, the radio-control facet of the hobby took a quantum leap forward with the advent of modern digital proportional control as pioneered by such companies as Kraft Systems, Orbit, Heathkit, Micro-Avionics, EK-Logictrol, Cannon, World Engines, and others. These modern radio-control systems allowed simultaneous and proportional control of the ailerons, elevator, rudder, and throttle functions. Along with these advances came the rise in popularity of the new nickel-cadmium (Ni-Cd) batteries that permitted us to operate radio systems for long periods of time. We could then quickly recharge them, and they did not have to be discarded for many years.
