I have a feeling you are right. I think we can use GA as a good example here of what can happen if the idiots with quadcopters aren't regulated. It's unfortunate that we are caught in that crossfire. To be honest and this is more a gut feeling combined with what I see is that recreational multi Rotor use is down. The MR racing seems to have taken off and is gaining popularity but those are low level flights. The use of MR aircraft in media production is up but those fall under part 107. Fixed wing FPV seems to be on the rise. Us humans are a funny lot, we continually look for challenges. If something does not challenge us for the most part we move to something else. Look at all the forms of competition within our society. Even our entertainment is full of competition. Look at how some of the conversations here on RCU get out of hand, some guys don't have their competitive needs met elsewhere so they bring it here. Bottom line is that for most people automated flight and assisted flight is boring. That's why right now we see guys being stupid and flying farther and higher, that's where their excitement is. Before long that will wear off and 75% of the guys will move onto something else. That is what keeps guys like me interested in R/C LOS flight, the constant challenge.
What does the future hold? We will be allowed to continue what we are doing now but with regulation. We will have to register, we will have to take a test, we will have to get fixed sites waivered. Places like Muncie in class G airspace will have to get waivers for specific events. The LSF ( special interest group for R/C soaring ) is doing that right now for the soaring Nats. This will become the new norm, LOS will survive, it will be just a bit more work.
