RE: Scaling to Keep Flying Characteristics
The only thing that does not change, model to full size, is time. Forget 'scale time'. If the full size covers its own length in one second, so will the model. The second is the same second. As for bank angles...if the full size takes 180 seconds to to turn 360 degrees, so will the model, but the physics will still show a much reduced bank angle for the model. You can try it yourself, but a 3 minute 360 takes a long time with a model, and it is a nearly flat turn...If you want to fly 'just like the real thing' then you have to scale the air to whatever scale the model is. And I can't think of anyone who has been able to do that yet...As stated, the 'fudge factors' for 'scale flight' are just that, and the best of them can be used to predict some full size performance data from models (wind tunnel stuff) but ain't no way to model models from the full size data.
