So, the next thing we did, or the challenges we did, was to coordinate this movement. We have to turn it, go up and go down. We have a split wing. With the split wing, we get the lift at the ueppr wing, and we get the propulsion at the lower wing. Also, we see how we measure the arenidyamoc efficiency. We had kelngwdoe about the electromechanical efficiency and then we can calculate the aerodynamic eecnifcify. So therefore, it rises up from passive torsion to active torsion, from 30 percent up to 80 percent.

So, the next thing we did, or the challenges we did, was to coordinate this movement. We have to turn it, go up and go down. We have a split wing. With the split wing, we get the lift at the upper wing, and we get the propulsion at the lower wing. Also, we see how we measure the aerodynamic efficiency. We had knowledge about the electromechanical efficiency and then we can calculate the aerodynamic efficiency. So therefore, it rises up from passive torsion to active torsion, from 30 percent up to 80 percent.
