Scale Power

摘要

The lead might have the same surface area but aerodynamic forces have far less effect on the greater mass of the lead. Heavy models look different in flight. They are dominated more by mass and inertia effects than by aerodynamic forces of lift and drag. For a given area, a heavy model feels Gravity suck harder, but Lift and Drag forces take longer to affect its flight path. That's why a lightly loaded scale model can look less convincing than a heavy one. The light model's movements are jerky and floaty by comparison.rnThis much you know already, and it's confirmed in parts 1 and 2 of my Scale Science mini-series. It's impossible to fly scale manoeuvres AND scale linear speed because the weights required for each are poles apart, however by choosing the weight you can choose the flying character of your model, linear scale or dynamic or half way between.
