Magne,
I never thanked you for your reply, but I did exactly as you suggested, I just used the throttle trim. The tip to shut it down BEFORE landing was also a good one, though I had to learn that the hard way by running off the runway as I was fumbling with the trim during the roll-out. Not enough thumbs to reduce the trim and steer at the same time.

Luckily no harm done.
Thanks for your suggestion.
