So i have to make a project of a uav at school. The criterias for it - Mtow 18 kg, Engine 2.0kw, and wingspan of 3 meters, Takeoff speed 45 kmh and cruise 80 kmh . The hard part is choosing a best airfoil for it, my first pick would be MH114 13.02%. So if anybody has a better airfoil to show than let me know, i would be thankful for it. and criticism is welcome. I added a picture of my first idea, contra-rotating propeller for eliminating prop torque, i made the tunnel stabilisator because i did not want that all the projects in the class would look the same :lick: wanted something new. :roll:
