Very good product, strong, good battery life, pretty shape. The presence of an elevator puts above all its competitors. A tip: To make the flight more realistic and more controllable extend the rudder depth of a few millimeters (5-10) with a piece of transparent Rhodoïd glued or attached to scotch.Entourer also the nose of the aircraft several rounds of scotch couleur.Il of the loops will be less easily but will have a much more stable flight. Good flights ... Bought a second unfortunately same problem as defective receiver Damien ... Too bad!
