With 6 acres, (one acre is about 200X200') you have plenty of room for a small park flyer like a firebird or something like that. If you want to go to something more capable, try an Aerobird, which is a three channel version of the fighterbird. Great plane. I love it.

As for glows being faster than electics, that is no longer true. many electrics can hit 50 MPH and some 100 MPH. And I am talking about the ones you buy in a hobby store or order through a catalog.

My Aerobird does very well in 10-12 MPH winds and I have flown in 15 MPH winds with some challenge, but it handles it pretty well.
