I have have all the warbirds. Plus, 3 F-15s 2 P-51s. They are soft by todays standards. But under 1 pound per square foot of wing loading is never a problem.
Most planes crash badly if the GWS COG is used on a hard surface runway. I adjust COG in DEEP field grass. Never a COG finding crash.
The A-10s were a beast with the Black & Decker 1100 A123 cells I used. The Hog had 1 speed. WOT & level.
The prop pusher A-10, was a vertical take off sweetheart.
