Weheka, I have about 200 hours jump flying in a 206 and have forgotten the trim once. From memory I had 6 jumpers on board so it was a very heavy load, and the pitch up was quite violent. The force I that had to use to push forward was massive and not easy at all. Luckily I was strong enough to be able to do it. I don't know how strong the pilot at Caboolture was, but I'm sure a lot of the slighter pilots out there would not have the upper body strength to be able to push the nose down. Needless to say, I never forgot the trim again.
RIP to those involved
