...But all that said, there is no shortage of planes that fly very well and could be used as a trainer. 4*, every cub I have ever flown, Stiks, tiger II, I owned a dynaflight fun scale P51 that flew very stable and docile (I miss that one any one know where I can find another kit.)

BUt in the end these are by and large not trainers, and to advertise them as such is what this thread is about. Its really not fair to the new guy/consumer. The free and well founded advice around here is to not try learning alone, so it seems odd that there are some companies that are marketing planes with that notion in mind when the true experts, us say its a silly, lonely way to kill balsa.

As for the question of what can be used as a trainer, the simple answer is anything right up to 200+ mph turbines. the only limiting factor here is how much money the student has and how much challenge the trainer wishes to take on. but again the question is really about the nomenclature. Is it is or is it aint a trainer in the true sense of the word. is my GP .60 cub? No, but I bet I could train anyone with average eye hand coordination and depth perception.
