[QUOTE="mrdetonator, post: 10870, member: 13"] [quote="Dilbert"] Eleven positions sounds rather complex, for a task that can probably be done with two (or one, if the gunsight were larger), but I guess that fully answers the question. I'm surprised that there seems to be no manual available for this plane.
