As for range, I am fine with what we have now for our cars. I can drive farther than I can see with the awfulest of Chinese offerings, and that becomes a shorter distance every day. Pretty soon the old cheap FM transmitters will seem to be way over-engineered for my eyesight
And as far as the FPV stuff, the government is not content with civilians having any kind of flying devices, and I believe they will slowly take away freedoms of people until the only place we can fly them is a tiny spec of land in the middle of Kansas off I-70. Oh, and mind the encroachment of the endless line of grass on fire heading your way, being driven by the wind. And the flaming tumbleweeds which are moving at speeds that are often seen outrunning cops in a high speed chase.
This alone makes me think the future tech we see in the RC world may start to slow down if the governments have their way. RC fanatics of the aerial nature were marveled by technology that allowed us to build drones that could fly many miles away from us. And you can still build them and buy them. You can fly DJI drones for miles away from you. But that is now illegal in a lot of places. So before long, they won't need to add that kinda range. That's like "Reverse Technology of the 2nd kind".
And before long (if they haven't already started the process), the electronics will likely be required by law to shut down once they are out of your line of sight, or won't be allowed through customs. Just speculating here mind you, and yes I am reaching, but something like this could affect a lot of things in this hobby. Not just drones, in the very near future.
I find it kinda tragic that we finally reached a point where we could see so much of the world through the help of RC and FPV technology, and before long they could take it all away. They are doing it slowly, right before our eyes. And most people don't see it. And without advancements in our hobby, the lack of joy will be leaving my kiddo to find better entertainment staring at a screen in his hand versus going outside and driving an RC car. Because by law maybe it can't be more than 50 feet from you traveling at a maximum allowed speed of a whopping 15mph.
Or maybe we will all have rocket ships!
