I recommend to people having trouble landing her, to practice some slow flights.
@ 220 - 200 kph in dirty configuration (gear down, flaps on landing) and you try to play near the stall speed doing climbs, descents, turns to certain headings etc.
What's important is to use use power to change altitude (or control VSI) and pitch to maintain a certain air speed.
You'll learn how the torque has enormous effects and how you need very small corrections on the stick. If you're using too much correction she'll be gone, you have to let her stabilize by herself.
And do that at a secure altitude of course :)
I'll try to show some videos of all that (T/O, landings, slow flights etc...)
