Despite what many may think, the PZT-28 Trojan is NOT a suitable plane for abeginner. It is, after all, a warbird and needs to be flown like one. If the newbie has access to a club and instructor, then I would say that it is possible to learn on a PZ Trojan. A great 4 channel trainer would be the 53" wingspan Hobbyzone Glasair Sportsman. I have seen a beginner fly one at our field and they are pretty nice. It does come with the "Virtual Instructor" (VI) technology but that can be switched off once the newbie gets comfortable with the plane. It also has the AS3X 3 axis stabalization built in. I'm stil on the fence about AS3X, but my experience with the HZ Firebird Stratos has convinced me that the VI does work.

Another good 4 channel plane would be the Ares Gamma 370 Pro bought with the non-aileron equipped wing from the original Gamma 370. The newbie can install the non-aileron wing on the Gamma 370 Pro and use it as a 3 channel until they get comfortable with the plane. The Pro version of the Gamma 370 comes with a brushless system installed. Once able to fly the 3 channel wing well, then the newbie can install the 4 channel aileron wing. You would be basically getting 2 planes in one for around $130.00. Less RX and TX of course.
