They're available at [link=http://www.hobbytron.com/MiniTypeFlyerRCAirplane.html]Hobbytron[/link] for $20. Looks like (from the video) you have to feather the rudder when turning.

They also have [link=http://www.hobbytron.com/Watt-Age-Parts-Landing-Gear-Micro-Flyer.html]landing gear [/link] for the micro flyer that may fit an AA for $3.95. Don't know how much they weigh, though.
