If you can't fly indoors, wait for a very still, windless day to fly your RC aircraft.
This isn't just advice I've heard from others and decided to pass along. I'm speaking from experience. Don't just stand still and see if there's any wind blowing on you -- look up. You'll be flying up high usually. Check the trees, the tree tops, and even the clouds for movement. Certain heavier aircraft can withstand slight breezes but watch out for gusts of wind.
