Slowly but surely.

  The recent problem with remotely controlled drone aircraft has put the radio controlled modeling community in the spotlight. There are model airplanes that weigh over 100 pounds and require more than one person to fly it. It's not hard to see the concern of the feds here. The people who fly model airplanes using wires to control them are almost immune to being called a drone and therefore being regulated out of existence. A lot of these modelers dislike r/c as a general rule. I find it funny that these same people are finding ways to control control line planes using a radio. The Navy carrier group and others are using radios to control the engine speed for their slow flight and landings. Some using insulated lines and others radios and receivers just like an r/c model. I just read about one person that made a bellcrank with a Hall effect device that controls r/c servos that move the models control surfaces. And the building of 100 inch wingspan control line models is gaining popularity in a few areas. And the builders are using some form of radio control over the engine. Not many want to be pulled around the circle by that big of a plane though.
 But if all that is put together by someone that has no knowledge at all of the modeling hobby that person can only conclude that r/c and c/l are one and the same and should be regulated to near extinction.
