RE: Did I buy the wrong plane?
When you're ready to try them, you will be surprised at how well some of the flatouts handle a moderate breeze, say 10mph or so. Great Planes has a couple of new "combat" style flat outs that are $24.99 retail, the zero and the hellcat, that could be gentle enough for you to give a try.
There are a lot of good park flyers out there, but the building requirements vary extensively. With your only stated flying experiences being with the Aero Aces and the Sky Fly, I wasn't sure if you wanted a project like the GWS Slow Stick or the Great Planes BLT kit that would require some assembly or building. Is "ready-to-fly" a prerequisite for your next plane, or would you like to take on a project with a little more assembly required?
