If my r/c helicopter can only fly up to 15ft off the ground, will it work in a 3rd floor apt?

i think it will because the 15ft probably means until the controller will no longer send the reception to the antenna on the RC helicopter not because of the thickness of the air or anything like that so you should be good to use it in a 3rd story building

I dont understand why it would be limited to 15 feet unless thats the radio range ? The barometric pressure would give 15 feet differences in altitude on different days so its unlikely to be a pressure altitude limit .

Simple method is a practical test, try it , just dont fly it out a window . :(

It’s not your actual elevation above sea level, it’s has to do with the helicopters height above ground. It is something called ground effect. Kind of complicated to understand without drawing. Your compressing more air further off the ground (poor wording by me but it’s getting near bedtime). When airplanes are landing they always encounter “ground effect”. This happens at an altitude approximately equal to the wingspan. If you fly your helicopter off a third floor balcony you may have a prob. However, it should fly the same in the penthouse as it will on the sidewalk.

yes it would, but do not let it out of window /it means operate it indoors/

hope you don’t live in Denver… you might have have to move to the coastline, or buy a new helicopter :)
