This kite is compact and travels well. When flying it on the beach or anyw it will always draw a crowd of people who will ask "w did you get it, and w can I get one?" It happens every time! Many have called me and said "man I could have sold a hundred of them right t!!!". If you doubt this, then just wait and see! Scientific Explanation : The "rotors" are actually more accurately described as wings, which are rotating around a center pivot, but with similar performance characteristics to those of an airplane. The obvious exception is that an airplanes wings are moving forward. The air travels over and under the wings just as on an airplane. The shape of the wings is that of an airfoil, which has a convex upper surface, and a flat lower surface. The air traveling over the top of the airfoil moves at a much faster speed than the air traveling accross the bottom surface. The faster moving air on top creates a lower pressure which causes the wing to be sucked or pushed upward and lifts the weight of the aircraft, or in this case the copter. The rotation of the "rotors" on this copter is caused by the pitch on the wing. The wing is pitched ever so slightly forward. When the wind hits the bottom surface of the wing, it causes the wings to rotate in that direction. Think about a windmill, with giant rotors spinning because of the pitch each fin has. It may sound scientific, and it really is very educational, but the fun you will have flying the copter will make you forget that you actually learned a very in depth aviation science lesson. How to perform stunts? Touch-n-go Landings - are performed by releasing a length of line very quickly to release the tension on the flying line. As the copter sinks out of the sky and approaches the ground, the string should be pulled in quickly. With practice the copter will just touch the ground and then power back into the sky. 360 Flat Spins - are performed only in strong wind conditions, with much practice. The copter will often "wash" back and forth in high winds. By timing a 10-12' release of line at just the moment that the copter reaches the outside edge of its flying pattern or "wash" the copter will spin completely around and may loose a little altitude. This trick is difficult but with a few hours of practice it becomes quite easy. Pin Point Landings - are performed when the pilot becomes used to the wind conditions and the angle of attack of the copter. A really great game is to try landing upright on a specific target. A gentle release of line, will allow a delicate landing which will keep the copter upright. 360 Rolls - are the most difficult stunt to perf... read more
