	Yes.  His scheme just used a receiver and a mechanical stepping
arrangement for the controls.  Thoroughly practical and guys built RC
models that was as early as 1918. There were "Radechon" toys built in
Japan for several years which used a spark transmitter and a simple
coherer receiver, followed by a motor-driven drive and steering
mechanism.
