The trick is not "draggy" plane, but simply better airfoil. Many guys try to use thinner airfoils for electric, but it does not work, because thinner airfoil has less drag in level flight, but when it comes to high G loads, with heavy battery, it reachs end of its ability to make enough lift at low drag, and all works just opposite, it brakes in corner. So they have low drag in straigh flight and high drag in corners, just opposite we want. The proper way is airfoil wich works well in corners, not in straight flight. Higher drag in level is not bad, and low drag in corner is goal. Some guys does it with thick airfoils and some with good configuration :- )))))
