It took several attempts, but I finally got it off the ground. A combination of small wheels and bumpy grass made it tough. (My son is behind the video camera.)
This is the NitroPlanes P-51 Mustang 31.5" Electric R/C Airplane: nitroplanes.com/93a275-800p51-blue-rtf-24g.html It's definitely the smallest R/C airplane I've flown. 31." wingspan and weighs just under 1 pound.
Pro tip: The bigger the plane, the easier it is to fly. Small R/C airplanes are a beast to control, as they're susceptible to any wind and generally they don't remain in flight as easily. For more advice, see my comments on this Flickr photo: flickr.com/photos/authentic/4753073373/
