Ah! Now I remember. I think it was Flying magazine that set up a "let's resolve this once and for all" experiment. They got an aerobatic plane, like an Extra, which had symmetrical airfoils, so it flew the same speeds and attitudes upright and inverted (more or less). They climbed it out on a 360 heading, and both upright and inverted it wanted to go west, and needed east rudder. Case closed. It's all P-factor.
Except…is there much of a relationship between an indoor model with two lifting surfaces, and a 500 HP Extra?
