3X Carbon Fiber Model Aircraft Assembly Flapping Wing Aircraft DIY Model Aircraft Pterosaur Rubber Band Bionic Aircraft

1.Flight model's instructions of parts design are more scientific, flying like birds,Is the preferred DIY assembly model, an upgraded version of the dove, the shape is more realistic, more simplified construction, increased wingspan and fuselage improve endurance and flight attitude. Nose, tail and other parts are made improvements, large wingspan, flight attitude become even more beautiful. 2. Parents need to give some appropriate guidance and help if the kids are too young. Turn up tail elevation angle of about 15-30 degrees, with the domestic rubber ring 80 power , learn to use the counterweight section adjust the center of gravity, to keep a flight balance, in order to fly well. Imitating the flight principle of birds, the angle of climb and the radius of flight can be adjusted. It is suitable for all kinds of extracurricular science and technology courses for middle and high age groups. It can understand the principle of crankshaft transmission and aviation knowledge through assembly; it can carry out the rubber dynamics staying empty race; effectively improve the students' hands-on Brain ability Aerial Photography: No Features: Remote Control Type: Airplane Controller Mode: MODE1,MODE2 State of Assembly: Unassembled Kit Age Range: Grownups,12-15 Years,more than the 8 years old,more than the 14 years old,8-11 Years Remote Control: Yes Control Channels: 4 Channels Model Number: Bionic Eagle Power Source: Electric Item Name:Imitate Birds Assembly Flight Toy Flying time: 20-30 seconds Weight: About 240g colour:black Material:Carbon fiber + ABS size:Wingspan: 46.5cm Wingspan: 35.5cm Package Contents: 9 x bag assembly parts 3 x wing spread 3 x rubber band Only the above package content, other products are not included.
