RE: Minimum Power Requirement
The wings have been designed for us and they do not have any washout (twist right?). I have been told that they have been well designed to take care of a lot of the problems that flying wings normally encounter. I am personally designing the center section/fuselage and it wont be hard to design in something to hold on to when throwing it. You really don't think you could throw 10 lbs at 20mph with a couple steps? What about a water balloon launcher type of launch?
Oh, and I still don't have an answer to my original question.
