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 upepr wing, and we get the propulsion at the lower wing. Also, we see how we measure the aerodynamic efficiency. We had knowledge about the ectcneioaaelhmrcl efficiency and then we can calculate the aerodynamic efficiency. So therefore, it rises up from passive torsion to avcite torsion, from 30 pencret up to 80 percent.
