well, a few things to consider. with the exception of the lt-40, almost all .40 size trainers will fly the same because they have the same charectaristics. it's the characteristics that really make it fly the way it does. moreso, on a trainer, it's the wing, and feathers that make it fly the way it does. the fuselage just holds the whole lot together. trainers have the wing on the top, with dihedral, and approximatly the same airfoil. they also have the cheap plank style wing wich gives you better low speed handling. also, given that there is only about a common 4 inch variation in wingspan of most .40 size trainers, the fuselage has to be somewhat perportionate, leaving the feathers to have to do the same thing. so there you have it. a complete breakdown of a trainer. the only real difference between your average .40 size trainers is the covering job. generally, the more you pay, the better made and better looking covering you get. ther e are always exceptions, and they should be mentioned. to be really honest, most of the seasoned guys at my field have told me the same thing. they said it doesn't really matter what trainer you get because they all do the same thing. they are designed for the same purpose. basically, and this ixs the general rule of thumb for things like this. things designed for the same purpose for about the same price, work jsut as well.
