The 120 is an airplane that was over designed. When I typed on it I had two years in the right seat before the type ride. It is an aircraft that runs on DC power not ac like most transport aircraft. That is quite confusing for most. They set up the instruments alot like the 57/67. It is an a/c that will tech you how to fly. Always stay on top of it. Other than that it was a blast to fly, but I was glad to get off of it...
