Also, it may interest you to know that I ran the dimensions of a B-52 (weight, sweep, chord, airfoils, etc.) through those "horrible" models, and the results in terms of stall speed were only 3 knots off actual. I did the same for several full-scale aircraft and achieved similar results.
So while the graphs aren't "pretty," they're pretty accurate, and certainly good enough for R/C model use.
ETA: Yes, I adjusted for the different Reynold's regimes.
Going back to the old RC modeler articles, they included formulas for calculating all of that based on overall weights, wing moments (CP vs CG, also airfoil moments), etc. Good resources - I have yet to find anything as good out there on there Internet!
