The thing that niggles me wrt to the single functional trim tab is this statement from the link I posted earlier.
"He was warned about the forces being put on that one tab."
Did the previous incident of trim tab failure not give cause for concern?
I know it's a human trait to believe that it can't happen to you and I hope that the rest of the racers are making suitable modifications to their awe inspiring aircraft.
Incidententally, does anyone know what happened to Learfang, the P51 with Lear jet wings?
