David,
As you know I no longer fly. I did fly several of these several years ago. A youngster brought me his to check out for him, it was a little tail heavy. Upon release I did the tightest loop you ever saw....I swear it spun in one spot. I then rewrote the stunt manual, it flew all over the place and was quite unbelievable in its performance. Well that was a good Cox engine...but to answer your question: I have never seen anything but Cox engines on them but I am sure that properly balanced it will do all that you want it to do.
