What kind of engine, and were any mods(valve seats pumps etc) made?
Simviation: Microsoft Flight Simulator Addons
Although the first examples reached the Western Front before the Sopwith Camel and it had a much better overall performance, problems with its Hispano-Suiza engine meant that there was a chronic shortage of S.E.5s until well into 1918 and fewer squadrons were equipped with the type than with the Sopwith fighter.
That is so totally cool. Well done.
