I used the cubic loading program to see what I get with my 3D planes.

1/4 Extra is 28.8 oz/sq ft wing loading.
Cubic loading for that one is 10.33.

In the real world it flies light, good 3D!


35% Ultimate is also 28.8% wing loading.
Cubic loading for that one is 7.58.

In the real world it flies very light too, good 3D. I find it just a little better than the little extra, but then its a bipe, two wings seem to get less lift that one big one over all.

35% Extra with a whopping 34.21 oz/sq ft wing loading.
Cubic loading for that is 9.81! Hmmm, less than the little Extra, even with a much higher wing loading.

In the real world it flies as light as the little extra, soooo I can verify from my experience that its all rather accurate.
