Rienk,

 

I think Peter Garrison that you are quoting above is referring to the 320/360 series aircraft  and not the IVP that is the center of this discusion. Have you flown the IVP and evaluated its flying qualities? Are you qualified to do so? Not to appear to be offensive here but are you an aeronautical engineer or possess some other skill, talent, training and background that gives rise to your opinions?

 

Regards,
