The rudder was too small in the Dr-1 .. directional stability was barely marginal.
Mr. Fokker knew this and actually told the fighter pilots that demonstrated the aircraft to use it in their performance evals ..if rudder was kicked into the torque side of a turn the Dr-1 would literally swap ends in a plane length, and it was so small and had so much lift it didn't stop flying when that happened.
It described a very small 'U' in the sky.
Werner Voss used that extremely well, and got over confident.
Obviously he was hopin for a lethal hit but accuracy was problematic.
Frik-kin spin dweeb.
