say no to the kingair and get into that seneca with no strings attached....fly safe though...esp when instructing...
multi engine instructing has NO room for error.
I know one person who bought a beech travel air to teach in it...screwed up a one engine go around and crashed, killing the student and harming the instructor for life.
I did multi instructing for quite awhile and everything was ok...just never, never let down your guard esp at low altitude.
seneca is a nice plane
