Just started flying a 604
Picked up a gig after retirement from mostly 121 flying. What a screaming piece of **** this airplane is. Phugoid instability in all three axis. Trim motors that move way to slow and every time you turn around there is a silly little component that needs replaced that cost 20,000 dollars. Spent my career flying mostly Boeing and Douglas airframes, this is a joke compared to those airplanes.
