I was taught to fly it like a jet by the numbers and not by feel
This comment was also made by a friend of mine that had a lot of time on MU-2 night freight ops.
He noted that a lot of the incidents were from pilots who were coming off piston twins and they were trying to fly the MU-2 like a 402.
Also when the tip tanks are half full minor pitch changes are amplified as all that fuel races from either end of the tip tanks , I did about 100 hrs in the right hand seat and it took me ages to work out what was going on. I was hand flying and got the aircraft all trimmed up and then it would pitch up, stabilise , trim and it would pitch down. It turned out the captain was just easing a bit of rudder on to initiate a minor pitch change and the fuel in the tip tanks would take over from there. When I worked out what he was doing I looked over and said "you bastard !" and he belly laughed for about 5 mins with tears coming out of his eyes. He said the look on my face when this was happening each time just cracked him up.
