Sin City, the flaperons (i.e. ailerons) follow the flaps through a multipoint mix (FLAPS to FLPRN). You can mix in any flaperon position you want for any given flap position, so it is possible to get three crow settings using the flap switch. At least I think that is what my 9303 is doing! Seems to work on a BobCat and a recent scratch build.
