From my earlier days of scale model building I would not rely too much on the accuracy of a Revelle model. I recently completed an 80" wing span radio controlled P47. I bought a Revelle 1/48" scale model of a P47 to lay out panel and rivet lines on the larger model. Found out real quick that the panel lines did not match from side to side, also the wing profile was way off. I ditched the Revelle model and bought a Hasegawa that was much more accurate, but still had problems. Point is, you will only obtain accurate measurements from a full scale subject. When you try and scale a scaled down version to scale up your measurements are not exact and the inaccuracies are amplified by the scale up factor you are using.
