My vote would go to the Great Planes PT-40. Great trainer! I also like to take out some of the diehedral, throw a O.S. 46 fx up front, and modify the wings to accept servos for each aileron. Nothing like a vertical capable trainer with a fast roll rate! LOL!

I know I might get flamed for saying that but I believe by doing this it will allow the trainer the ability to grow with the airplane, of course I only do this for people who have asked me to build there trainers for them, probably too complex for a first time builder. Just thought I would share my ideas!
