The Solar Impulse 2 is an electric plane that runs off of solar energy. Its four engines are electric and have 3 metre long blades. The true top speed of it is 50 mph. It is flying around the world and it began its voyage in Abu Dhabi and is going to land back there at the end. To fly mine put the VTOL to about the top middle bar, to fly closer to the true top speed put the VTOL just above the middle. To retract the landing gear press1 (it is hooked up to the throttle). Whenturning it is best to roll the opposite direction you want to go and pitch down. If you use yaw be careful because the plane tends to never stop turning with it. Have fun with the plane of the future!
