I did not say that the trim was innefective, but once trimmed that is pretty much it, when training you want the trim changes that you get with change in power/flap in order to get the student in the habit of using the trimmer - in the Cessna you get those changes, in the Pa38 you do not because of the T-tail!
But why so much emphasis on the Pa38 Vs Cessna, I have already said I am not an advocate of EITHER, personally I would rather a Beagle Pup, Chippie or one of the 2 seat Robins but for spares/finance these are not realistic for most clubs
