Hey Guys,

First time on this forum, please excuse me if my posting is not quite right.

I'm thinking of flying my ultralight aircraft, the 2-place Weedhopper, down the coast of South America. I know it's crazy, but it's the good kind of crazy :). It's a little tricked out to get much better range.

Anyways, I am curious if there are any online sources where I can find which airspace is uncontrolled (class F and G). I'm not an official pilot, but I do have my solo license. Sources would be much appreciated.

Thanks for any advice.
