The 1938 King's Cup Race was a 1,012 mile event and this time, Alex Henshaw's much modified E2H "G-AEXF" came in 1st at 236 mph and Giles Guthrie in his red "standard" E2H "G-AEKL" placed 2nd. Henshaw's win set a class record which, as of 2020, still stands. Edgar Percival flew a third Mew Gull, the E3H ("G-AFAA") and finished 6th. Percival might easily have won, but as well as being made scratch-man by the Handicappers, he left the fine-tuning of his airscrew pitches until just before the race and his ground-crew were still tinkering with them as Alex Henshaw took off. At this time the Bracket-Type airscrew simply did not have the pitch-range to cope with the exceptionally wide speed range of the E3H (59–265 mph). An optimisation for either cruise or takeoff and climb would inevitably compromise the other.
