My brother had a TT trainer 40 that he bought used. His had a plastic cowl and a plastic turtledeck that made it look more like a full scale plane than many other trainers. The plastic parts got broken during typical newbie mishaps, so it didn't look realistic for very long. The plane had a strong tendency to climb even at low throttle settings. A popsicle stick under the trailing edge solved the issue and it flew very well.
