Depends on what you buy.
I know it doesn't matter for me what brand/type of radio I use, but I've never gone over a $100 radio. I've had a traxxas qt3 (or whatever it is with the 2.5 maxx), JR XR2 (AM) and what I'm currently running, airtronics MX-3 FM. All of them get the same crappy range which is around 100 yards. But it seems to be mostly due to where I have to drive. When I was at my parents (middle of podunk IA), I could drive further than I could see... they are near nothing but corn fields.
Here in dekalb, I get glitching periodically and a 100 yard range typically. Must be a lot of radio waves floating around...
The reason I say it depends is because I know from reading that the spectrum module system and nomadio system goes really really far. But they are both above the $300 mark I believe. Nice radios, but more than I need by far.
