Product Description: Lightning Fighter Item code: FJ602-618 Packing: 144 sets/box Color: 3 colors Size: wingspan 395mm, length 330mm, height 175mm. Color box: 34.5*10*4cm Box gauge: 83cm*44cm*69cm Single weight: about 100 grams Teaching points: rubber power cabin aircraft assembly model, simulation style, puzzle assembly, introductory model training, training to improve flight level and technology. Simple assembly, 3D cabin, leaving it blank for about 15-50 seconds, suitable for popular aviation model classes to carry out scientific and technological activities. The model airplane is a junior trainer, who can learn and debug the aileron of the main wing and the aileron of the horizontal tail to control the flight attitude. The flight take-off angle is usually about 15-20 degrees. Product advantages: the aircraft dynamics enlightenment can improve the hands-on ability, and the longest flight can be about 15-50 seconds. After the baby is made, you can learn to control the flight attitude through debugging. Pay attention to the introduction of low-power flight test first, then high-power flight, avoid collision and fall, and choose a safe open area. The wind is too strong for flying. First, view the model Looking directly from the head of the model, the well-installed model should be undistorted and symmetrical. Second, the model adjustment When there is no wind or breeze, hold the center of gravity of the nose and gently throw the model. Adjust the fore-and-aft distance of the wing platform according to the flight attitude of the model. Wave flight means that the head is light and the wing platform needs to be moved backwards; A downward dive indicates a heavy head, and the wing platform needs to be moved forward. Third, power flight First, turn the propeller clockwise about 15 times, then hold the propeller in the right hand and the left hand, and gently push it out in the wind. Observe the flight trajectory, and the hovering attitude is the best. If it is found that the hovering radius of the model is too small, just cut the root of the vertical tail and bend it in the opposite direction. After the flight attitude is normal, fly around the rubber band for 200~220 times with great power. Rubber bands should be straightened and slightly relaxed at ordinary times. Personally, I think it doesn't matter whether it is oiled or not. If it is oiled, it will turn a little smoother, but the life of the rubber band will be shortened. The key problem is to adjust the center of gravity of the aircraft. The method is to throw it directly from your hand in a windless environment without tightening the rubber band. The plane can neither raise its head obviously nor lower its head obviously. If you look up, add a counterweight to the nose. In addition, it is also necessary to pay attention to the fact that the aircraft cannot roll, and if it does, adjust the wing correction left and right. During the competition, you should generally throw the plane against the wind without using too much force. Especially when the wind is strong, the force given by the hand is large, and the plane will do somersaults backwards, which will shorten the blank time. Precautions: Step 1 fly Flying this model is not suitable for flying in crowds and near roads, high-voltage lines and rivers to avoid accidents. 2. Younger children should be accompanied by adults when flying. The airplane model has good flying ability, but it doesn't fly when it is released. Face people and animals. Choose a safe area to fly, when to pick up the plane. When driving, pay attention to vehicles and roads.
