With a little time in the 407 I always thought it was going to be a nice machine. The Motto I always carry is "Never fly an A model of anything" it most certainly applies to the 407.
I met one of the 407 drivers in SA who had one of the failures a year or so ago. He was not thrilled with it for sure. By the comments here it appears the T/R has the ability to touch the tailboom under certain conditions. To me thats a No No......pedal stops or not.
