Yikes, from the replies I've started a conTROVersy. Watching in the TA using external , from stop to takeoff, no dust from tail wheel.
I've accelerated to speed, guessing maybe 75mph and stopped, still no dust.
Compared to other P-47 variants, this was the only dust free version.
Just looked at it some more in TA. If you get the tail wheel off the ground and apply brakes and pull back on stick, you do get a puff of dust when the wheel hits the ground but not as it rolls along.
