No.

Trainers with similar airfoils will exhibit all the characteristics of that particular wing section, but that's where true commonality actually ends. Of course, if many of the other design incorporated features are virtually identical from one particular trainer to another, then what's in a name or covering, naturally it's the same rose of a different colour. As there are basically a number of characteristics which are desirable in a good trainer to enhance and accelerate learning, eg: high straight rectangular wing with positive dihedral, trike wire undercarriage, uncowled upright mounted engine, then to the uncritical eye, most trainers look the same, and to the equally undiscerning 'driver', fly the same.

Though both high wing with all the commonalities mentioned above, an example of two trainers which are completely dissimiliar both in appearance and handling would be Phoenix's Classic and SIG's LT-40. And two which bear close visual and design resemblence which fly similarly, Global's RCM Trainer 40 and VMAR's Discovery.
