For the sake of completeness, I would post (after dozens of frustrating attempts) that eventually found my way to land safely (enough):
- Descend on final at a reasonable glide slope, trim neutral (the one you get hitting Shift+Up Arrow) getting descent angle by throttle, stick neutral.
- Pointing at runway start, flare when close and GRADUALLY reduce throttle, while keeping aircraft as low as possible.
- Let the aeroplane stall and touch down, cut-off throttle and brake at short intervals, keeping alignment with runway.
Only the touch-down takes to me about two-thirds of runway lenght. I'm unable to point earlier since I need runway edges as reference to keep alignment during the very long "floating" time between flare and touch-down.
I posted here just in case could help someone who has problems with landing in 4.11.1.
Curiously, I did dozens of landings in RL with ULM's of five different models; Ok they're not monster with thousands of HP, but are also much lighter and smaller - it's all in proportion, so to speak - and never had such difficulties, like plane bouncing for meters higher than runway for slightly hard touch-down, neither tendency to roll upside-down cutting-off from a 10-20% throttle.
