RE: T-28 Trojan?
Normally the answer to using a low wing sport plane as your first trainer would be no. If you are referring to the Parkzone T-28 though, you might be able to pull it off if you fly on low rates and have help from an instructor or experienced flyer. It is a pretty forgiving and surprisingly durable airplane.
If you are referring to some other T-28 such as the glow ARf from BH Models then no way.
