To show you that Bob also thinks about receivers, at top is his first, from 1953—the Miller—which was featured in MAN that year. It weighed 5 ounces and offered only single-channel control of rudder. In middle are typical, current Futaba and Airtronics dual-conversion RC FM receivers. At bottom right is FMA Direct aftermarket receiver. At bottom left is popular 0.2-ounce GWS R4P micro four-channel receiver.
