If you did want to fly in the back yard, here is the plane to do it.

A cool little flyer that you could fly in your yard or in
front of your house? For the all out cool factor, this would be my first choice - The IFO

The I.F.O. Aerobatic R/C Slowflyer -

As I understand it, this can be flown indoors in a gym, or outside in under 7
MPH winds. With the right flight pack, it can hover on its prop and is almost
indestructable. You could sit on your back porch and fly this around your
kids.

I have read that you can even pack this up in a suitcase and take it with you
on a trip. How cool is that?
