In some degree I agree, the same revised loading table also has limits for the modified elevators:
1. With modified horn balance elevator (Spitfire modification No. 789): - 9.0 in. aft of datum point.
2. With Westland convex elevator (Spitfire modification No. 743) - 8.2 in. aft of datum point.
Note: - 1. & 2.apply to all propellers no elevator inertia device should be fitted.
So there indeed was design changes to solve the problem but I won't call that as a design problem because the loading needs grew over the original specification.
Over and out
