Yep, no in-game checklist, but there’s at least a thorough set of procedures in the manual, as well as checklists at the end.
I’d suggest sending feedback to Virtavia on the checklist if it’s something you really want to see. This is their first MSFS plane, so that kind of feedback will probably be helpful to them!
There’s a very slight hesitation and then it responds. Feels right for a plane of that size/weight/wing area, but I’ve never flown a heavy bomber IRL.
