RE: AOA and speed
YES!
If you look at the e-Flite T-28, which is surely the best scale model ever offered, the reason for its success is it's made of foam, and is incredibly light.
The full-scale T-28 has two "features" that make it a poor choice for a model.
Wing area and fuselage size.
If the model is rendered in conventional balsa-plywood construction, the resultant wingloading makes the plane a handful.. Takeoff speeds are high, as are lainding speeds, and these planes seldom survive long.
The e-Flite version, being as light as it is, is superb!
It's almost of trainer quality handling, but put in a slightly larger motor.. Power 10, and it will go vertical! NO T-28s can do that!
