Dan W - Hi to you, nicely retired and literally on the beach, thank you!!
Re. the crossover video, and, indeed, the others in that series, My INITIAL impression was that 'Van' was advocating 'aggressive' rudder inputs but the more times I watched it, the more I noted the caveats about inputs being conditional. It seems to me that not being aware of common and standard structural limitations vis-a-vis control inputs would lead to problems anyway. Although the crossover segment was part of the package, it's worth noting that the sequences were provided by the Boeing Test Flight people.
I still rate the series as one of the best teaching videos I came across in my time in aviation.
