I'm not argueing that our models don't have the same forces applying to them, I am simply stating that for the most part the forces are too small to be significant. There ars simply too many differences between the two other then size to apply full scale logic 100%. Take the following examples and by all means I am not a full scale pilot so correct me if my figures are too far off. For comparison lets look at a 35% Extra 300 VS a full scale Extra 300.

35% Extra wet weight 30 lbs

Full Scale 2,000 lbs

35% Extra max RPM 6,5000

Full Scale 2,700

35% Extra power to weight 1.75 to 1

Full Scale .8 to 1 average 1 to 1 at best

35% Extra wing loading 1.5 lbs per sq ft

Full Scale 17 lbs per sq ft


You can see where I am getting at. it's not really comparing apples to apples. A good example is that if I have no yaw on a full throttle level pass then when I come in at a high AOA slow pass then the Pfactor should have me yawing to the left. I assure you this does not happen. On all of my aerobatic airplanes to date, once set up correctly there is no yaw differences that I am able to see regardless of AOA. I'm just not seeing why people want to apply full scale principal to our models at 100% value? Can anyone explain to me why the above specs would not make any difference?
