There are far too many variables at play plus scaling effects to draw any general correlation between a full scale aircraft and a scale model in terms of flight regime. Generally models have to be built with very light wing loadings to fly at anything resembling realistic scale speeds. Linear dimensions scale proportionally, areas as the square of scale, volumes as the cube. Reynolds numbers go down so efficiency suffers.

Using a familiar example to me, a Tiger Moth might cruise at 75mph and they stall at about 45. Build a 1/7 scale version and it would have just over 4' wingspan, cruise speed would be 10.7 mph and stall at 6.4 mph. Now think about the weight and construction techniques required to build a 4' span model with those characteristics!
