Comments: The Sparrow started as a how small can I make this and then the idea of caraciture planes, IE planes that were recognizable such as a P-51 or ME109 but definitely an exaggeration of the original but something small and easy to fit into your truck.

The sparrow is fun to fly and one cute thing is it rolls like on a rail. But it needs too much power to keep it flying and has a very short flight time. On seven 600ma cells its only a 3:15 minute flight. There just isn’t enough room for more batteries. Maybe some new batteries will come along. Also with the little wing when you cut the throttle down she comes. It’s kind of like landing the space shuttle. You had better be lined up and on track down the runway because she’s coming in.
