Hi Peter.....
Avatar uploaded!!... This plane is a 3D Hobby Shop "AJ Slick" There is a full size aerobatic plane called a "Slick", but the model was designed by a young man by the name of Andrew Jesky. This video in Youtube...
http://www.youtube.com/watch?v=A3JWUjby8iE&feature=related is of the same type of plane, (just a different color scheme) as flown by Andrew. As you can see it has an extremely high power to weight ratio (about 220 watts per pound, and yes, these are electric) The wingspan of the model is 70" and is about the same length. This one came in just the two shades of blue, but the "Red Bull" stickers (or as we must call it to legally put it on our planes, "Crimson Bovine) were purchased and put on by me.
For a decent sport plane, you want about 120 watts per pound, for good aerobatics, about 150 watts per pound, for full "3D" flying, which is what you see in the video anything over 160 is good, 180 better, and over 200 will give you ballistic pull out from a vertical hover. My plane weighs in at about 9.5 pounds, and puts out about 2090 watts of power at full throttle.
Unfortunately, I am not as good of a flier as Andrew is (not many people are, as he is a champion flier.
