A lot of us older pilots who only flew with the little wheels were Grandfathered in as far as meeting the new requirements of getting an indorsement which came out in 1975 I think. That is not to say you retain your skill if you haven't played with one in a while. I flew a 170 some months back just like the first one I owned and you soon realize how lazy we trike guys are on the pedals. It is like everything else, you use it or lose it.
