Im having problem with the trim with the Turbo Arrow III but on final approach, I read somewhere that it was impossible to flare with the TCA sidestick, so I tried it out, and at short final I noticed I had the stick all the way pulled down, I was trying to trim up the plane, but it was not reacting as expected, I hit the runway so hard that I damaged the plane.. LOL. I tried then the Turbo Arrow IV, and that was way better, I was adjusting the trim in short final and the plane reacted accordingly and I was flaring nicely.
I need to check this "trim" setting on the EFB and see if it helps.
