I've flown the P2002JF a couple of times. It is a thoroughly pleasant aircraft with no real vices. Reading between the lines, I'm guessing that our OP is talking about the new Tecnams at Newtonards. Considering the fact that the club used to do the vast majority of their PPL training on 172SPs, the Tecnam is by far a better aircraft for ab-initio students to learn on. I will also stick my neck out and, having looked at the Ulster Flying Club website, I note that a student has recently solo'd after a total of 8hrs on the 152 and only 3hrs more on the Tecnam. Unless someone wishes to accuse the instructor of being reckless, I would suggest that this is evidence enough that the Tecnam is a very good aircraft for student training.
Paraphrasing Pace's thoughts - it is a simple single engined aircraft. Sometimes we try to complicate things that don't need complicating.
