Radios have improved leaps and bounds in their 30-plus year history. Not long ago, RC car enthusiasts were using stick radios. Eventually those stick radios evolved into radios with wheels and triggers similar to what we use today. KO Propo has always been at the forefront of radio technology and this mock up of one of their first stick radios is pretty cool. You could see that racers were looking for alternatives to pushing and pulling on sticks. Stick radios may work for plane guys, but we want triggers and steering wheels.
