I flew the merlin IIB. It had the original dash 1's. after getting airborne, we'd have to level off at 50 ft to build airspeed. She would not climb until it read 120 on the airspeed indicator. I only had 1 engine failure. But, it had the best pressurization system for a cabin class twin, the same one in the 226. Oh yeah, we also had a funny designation, the SA 26 AT.
