some excellent advice on here, fascinating.
i would like to relate a story an instructor told me many years ago.
paul was checking a new club member with tailwheel experience out in an auster. on the first approach he got the flare horribly wrong and made such a heavy landing that both legs punched though the floor. there was a moment of silence then the pilot said to paul,"some fxxxxing instructor you are", promptly opened the door, walked across the airfield and was never seen again!
