RE: Final decision trainer
Hey,
I can't speak for the other two but I have an LT-40. It is probably the largest trainer. It flies great! It is very stable. It has a fairly good size dihedral (wings are angled upwards) which makes it self correct. I like mine a lot. However the main think I don't like about it is that it does not roll that well. It will roll, but it requires elevator. I don't like that. But other than that I think it is a great plane. If it is trimmed right it practically flies itself.
Do a search on trainers and you will find tons and tons of peoples recommendations.
Best of luck.
