I've always been a "cono-sewer" of pre-flight checks. And it can happen to anyone. A month ago, I was at the field with 3 models.
Upon switching planes, did the usual pre-flight check of servo linkages etc. Launched my Sig Kougar and noticed that it needed some
right aileron trim. Flew the tank and landed. Only to find out that the selected model on my Futaba 9C was a Great Planes U Can Do.
So, I flew the Kougar on the U Can Do's settings. Boy was I lucky!!
