I can close this thread. I took a break, then realized I could run the tutorial again because I was interrupted while I watched it the first time, and was distracted. Went thru the full startup tutorial process, taxied, and took off and am now in cruise flight. It is interesting, as complex as this aircraft is, that it is fps fluid when other, less complex aircraft I have purchased in this niche for X-plane 11 can hit the fps a bit . Once in the air, flying the aircraft and autopilot management is as I expected, and I enjoy it better than the similar Carenado TBM project for Prepare3D4.5.
Figured out my door closing problem was caused by grabbing the door in the wrong spot, problem solved.
So I am in cruise mode now, flying from Sacto to Vegas, to see if I can win back what I paid for the add-on in a virtual way, lol...
