you have opened up the dreaded question. you do know though that most people are going to vote for the trainer they learned on because that is the only one they have flown. i am that way. i am not afraid to admit it. however, i do mention that i just liked the plane because it wasn't so docile you had to fight it all the time, but was a great trainer and would fly about as slow as i could run fast. (about 13mph) keep in mind, while bigger may be better to some people, as bigger gets better, the cost gets significantly bigger too. your choice, but trainers are all pretty much the same. before you reply in protest, some do have litle tricks up their sleeve, but all trainers are built for the same purpose (to be easy to fly, sel righting, no bad habbits, glide well) so they are going to fly pretty much the same. they all will have a high wing, most will have dihedral, they will mostly be trycicle gears, they will have cheaoper plank wings and boxy fuselages with cheeks instead of cowls. they will also have fairly small surfaces, a flat bottom airfoil, will fly very slowly without a problem and set up for a two stroke motor. any plane that fits these criteria will be a decent trainer.
