I've flown quite a few different trainers, and the LT-40 is probably the best I've flown....although quite a few were also excellent. These included the PT-40, Superstar, and Alpha. In my opinion, any lightweight balsa/ply trainer will fly better than the Aircore trainer.......the aircore might be somewhat "indestructable", but if you have help from an instructor with a balsa trainer, odds are you won't crash it anyway. If you need an indestructable trainer, check out the SPAD trainers, flight reports seem to be better than the Aircore's.
