Awesome video!
I wonder if this video would be admissible as a test regarding the roll rate of our own P-40E. At two points he makes the airspeed known, 200 and 220 mph.
"And you don't need full deflection, I've got uhh 220mph, that's plenty..."
A quick stopwatch gives me about 4.4 ish seconds for a full roll, limited stick deflection. Going to test our own P-40s right nwo.
PS, his mustache sucks.
