This is what I like about the MTBF theory. It's super realistic to go 100's of hours with no failures and then get two on the same flight with a new airplane. You just never know these things are going to surprise you which is what makes these aircraft so rewarding to me.
I just practiced an engine shut down last night, and I thought the feathering physics was amazing... Did you put the lever into feather quickly? They won't feather unless you do it quickly after shut down which is realistic.
