I would like to mention something about the flaps. I have NO authoritive basis for this, so take it as is (I'm sure someone will be along to correct me anyways ). I think those depend on the plane whether they help or hurt Vmc. I have heard that on the Seminole, they help by making it more stable. On the Baron, they hurt Vmc because they blanket the airflow to the rudder. Again, I have no real evidence of that, so if someone could give a bit more insight, I will have learned something new today.
