Despite Aeromaniacs posting the video, I'm pretty sure Heman wasn't at any of the Albany (and this was at Albany) NW CL Regionals...could be wrong, of course. So, I can't say who's video it is. May well be clipped from a Heavy Hippo tape (Bruce Hunt).
It also doesn't look all that windy in the video, judging from the banners on the safety strang, and the wind appears to be pretty much straight down the runway...a real good thing. FWIW, I never liked the PW-51's all that much. They didn't ever show me the blazing corner that the Impacts can do. Maybe because of the 4 strokes/bigger props? Paul is showing some good stuff in the video, as expected.
