Perhaps I didn't make my point as clearly as I should have. Yes, there are planes that can fly in small spaces. But a backyard is going to have not only wind but also obstacles. Experienced flyers may be able to handle that, but beginners are just going to crash. The Bug does look like fun but still should be flown in a bigger space than the OP was talking about.

I've been down this road before. I bought an UM 4 Site last year after about 3 years in the hobby. I wanted to just try it out in the backyard, and after a couple of 2 second flights and one that lasted nearly 5 and ended with a roof landing, I figured out I needed more space. I have a park nearby with about an acre of open space surrounded by trees that act as a wind break. It flies well out there on calm days, but any air turbulence makes it a handful. What I learned was that micro planes are made to fly well in big indoor spaces like gyms and hangars. You need horizontal space to maneuver in and you need vertical space to recover in.

If outdoors is where your flying has to be, then bigger planes that can take some wind are best along with the open space to move around in.
