I have been into RC cars for along time and I am looking at planes now. I bought an S2K glider from my lhs but I am not done building it. I am going to want a Trainer gas plane soon. I cant decide between .25 and .40 size trainers. Which would be the easiest to fly? The plane I have been looking at is the Right Flyer 40T or the RF 25T. Are these good planes? They are very affordable.
