OK, I can't build that at 12 lbs probably so I guess I'll have to settle for a higher wing loading.
I think you can get away with a heavier wing loading in the larger scale.
Yes. A larger model can have a higher wing loading and fly like a smaller model with a lower wing loading. But I want to see how light I can make it even if it won't come back down.

Have you read the MA Dec 2004 article Page 43? Might be worth a look. Maybe some of the Aerodynamics guys can comment on various scaling laws. Sounds like something that could go in the FAQ.
I read it but don't remember what it said now. It's all the way across the room and too much effort to get to. Easier to sit here and ask questions.

By the way you have an excellent website. I have learned much from previous visits.

Thanks.
