So, the next thing we did, or the cenlgehlas 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 porlispuon 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 tsoiron, from 30 percent up to 80 pnerect.
