Swing open windows + bugs?

I see a lot of designs with Wiley windows and windows that open outwards on a top hinge. I've been lurking around websites and yards and have found all kinds of used ones for cheap. From the beginning I thought about just normal RV/camper windows that slide sideways with screens. This won't work in the rain. Even having a small lip won't help much because often when we get rain, we get wind, and the rain is coming in at a 45 degree angle.
Looking at the flip out windows, I never see screens in them, same with the Wiley window setups. Are the screens just not showing in the pics? Is there a lever you slide to pop them out or do you push them out, hence no screen? And if you guys don't have screens, how do you deal with all the bugs? Over here, there's no way you can get any sleep if you're not in something enclosed/screened in, you'll get eaten alive by mosquitoes and horse flies!
Is there a design that flips out with a lever that allows a screen to be in place? I'd like that so I don't have to worry about rain.
Thanks!
