I have the 40 size Tower Trainer with a 52 Magnum 4 stroke on it, and I really like it. with dual rates, you can do some basic to intermediate aerobatics with this plane, although some of it does look pretty "ugly". But I like it well enough that its usually my first plane of the day each time I go out. Then of course I move on to the faster, more daring planes....... but I still come back to this trainer for some peaceful and relaxing stick time. So go for it. get this Tower trainer, and you won't be disappointed in it at all.
