Hello James
You ask an interesting question. As with all such debates, much depends on the context and there may be an element of subjectivity in my response. If I may first deal with the latter, I have to admit that I think the SE5a magnificent; a real thoroughbred.
The Camel was indeed a powerful, rugged aircraft and it is important to remember that it was the first RFC single-seater to carry two fixed machine guns firing through the propeller arc. Built in huge numbers, it was certainly an unforgiving a machine for the novice. Forgive me if I have the terminolgy wrong, but I understand that the difficulty stemmed, in large part, from the immense torque generated by the large rotary engine. I'm not sure if it's an urban myth but I have read somewhere that more than one Camel pilot threw off a pursuer by appearing to turn one way only to allow the torque to pull the aircraft round in a tight circle and escape in the opposite direction!
There seems little doubt that the Camel could outperform the Albatros DV and DVa, but one must recognise that a skilled pilot in a average aircraft was always likely to overcome a poor or novice opponent in a technically better machine. Pilot casualties in Camels were high, but again the context is important. While the glorious SE5a was engaging in exciting encounters at altitude with types including the Fokker DVII (which is why I think they would make an excellent WNW Duellist set), the Camel was performing valiantly at lower levels and in a ground attack role. Particularly in the desparate days of spring 1918, the relative lack of dedicated RAF ground attack aircaft (the DH5 aside) meant that the Camel was thrown into the vacuum as attempts were made to stem the last great German offensive. Not conceived for this role, losses from ground fire were horrific.
On one final note, while Roy Brown displayed real leadership skills in tracking May's plight and may even have saved his life by distracting Richthofen, the broad consensus now is that the single bullet which killed the German was fired from the ground.
Best wishes
