Humm, I am no expert but I had no problem. I set up a left hand pattern to drop altitude and speed. I like to be on final at 200kmh, prop pitch at 100 (fine) if you need the power you want it now, not wait for it to slowly pick up speed. I keep all 3 engines running during the landing. I have it to takeoff flaps on final, as I actually approach the beginning of the runway I hit landing flaps, going about 150kmh now. I watch airspeed, chop throttle and flare just above ground. If tail does not drop for some reason I raise flaps to get it down, but that does not seem to be a problem.
Found this site for an explanation on what the gauges are, as I fly with the inflight gauge info in the lower left corner of the screen turned off and you have to be able to find the gauges to fly.

At the bottom of the page is a link to the aircraft’s checklists. Nice page.
I also found the rather opposite engine / turning plane response as well when on the ground. If you know the peculiarities of the engines on the ground (seems to work opposite to logic) you can turn “control all engines off” and select the engines individually to really get you turning around on the ground pronto.
Still have to fiddle with the engine mixture settings as of right now, as I don’t have the drill down yet.
