I live in a condo and I will run my T-maxx in the parking lot or out in front of the condo winter or summer.. I haven't had any complaints yet.. I run my T-maxx and my nitro 4-tec in a school parking lot on the weekends when school is out because its a very large parking lot that was recently paved.. I have several electrics that I run as well, but they don't bother anyone.. I also have a Baja 5B that I don't tend to run at my condo because its just too loud..with the tuned pipe its sounds like a harley and a dirtbike on steroids.. I run that at the school field or the local quarry when they are closed... These nitro's aren't that loud, but you have to be respectful if someone complains... Unfortunately not everyone shares our love of all things radio control..
