It's a great video and insight to the mustering role but they do emphasise the handling differences from TR to Fenestron so I think '10 minutes' is understating the different way the Fenstron produces its thrust across the pedal range compared to a conventional TR ie it is more of an 'S' curve than a straight line.
Interesting that they all seem to feel safer in the G2 and prefer the responsive handling of the 3-blade system.
