The "Emil" was smaller than either RAF fighter, and it was more difficult to land and take off than the Spitfire and Hurricane. At high speeds controls tightened considerably, and the Bf 109E needed more strength to manoeuvre than either of its main opponents. Of all three fighters, the Bf 109E would possess the highest roll rate, with the aileron controls being brisk and responsive; the Spitfire had the highest aileron forces, but both the Spitfire and the Messerschmitt's rate of roll suffered at high speed.
