RE: low wing trainer?
It's hard to tell from the picture, but here are a few "no spin" obseravations on the plane:
1. The wing has a small amount of diehedral
2. In the picture the wing looks to have a constant chord, or possible a slight tapper.
3. The airfoil is symmeterical or nearly symmeterical.
4. Big vertical fin and horizontal.
5. The fat canopy will increase drag and make the plane fly slower and decelerate quicker.
Except for the canopy this is the same formula used when everyone talks about a "good" second plane: Hogs, four stars, big sticks etc. The biggest factor for this plane well be its weight / wing loading. If the plane is light it should fly very well and land easy. If the plane is very heavy then there could be complications, otherwise it wouldn't give a second thought to making it my second plane.
