I tend to agree with Super F . The 505 is , I believe , in a different league to the 66 .... but I would think that as I really don’t like Robinson’s at all !!!
I flew the 505 again last w/e from London to Yorkshire and was once again really impressed with it . Comfortable, smooth at 120 knots . I would still prefer another AS350 but you are talking double ( yes I really think an old 350 would cost that ) the running costs and flimsy cabin and crap seats . Just on the money side the 505 is compelling but is it a great helicopter ?
Not while it has 2 blades and TT straps !
