Namaste victor papa
Hmmm I guess You have not operated to much above 10,000' let alone 20,000' the fenestron is very heavy, very power hungry, plus runs out of authority very easy well below 19,000' nah no thanks give me a conventional tail-rotor for power & authority any day. But yes the 130 is very sexy just shame about the tail end of her hmmmm maybe we need a B5
Happy Landings
