Embraer EMB-312 Tucano
The plane is definitely a Tucano. Prince America makes a .60 sized fiberglass ARF. The plane looks like one of the DLAero kits though, I think it had a 72" wingspan. I think it is DLAero, or something like that, although they have quit making the Tucano kit they had. Aero FZD also has a nice Tucano with a 89" wingspan. Don Smith has plans for an 86" wingspan Tucano.
Anyway, it is definitely a Tucano and not a Havard II. The harvard has a sharp vertical tail fairing, the tucano is blended, and the horizontal stab and elevators are split on the Tucano by the rudder, verse the Havard has a one piece elevator with the rudder completely above it.
