Recently there has been quite a bit of interest in flying wings here on HBA, spread over several different threads. So to make it more organized, I thought I would start a thread just on this topic. I would prefer to keep it specific to "Horten style", with no vertical surfaces, but other ideas (winglets, close coupled rudders, Weltensegler tips, etc) are welcome. Questions are certainly welcome, but please try to back up proposals with some type of valid evidence, if you are proposing an idea. What I have in mind, for myself, is an LSA size craft with a range of 300-500 miles, cruise 120 mph, stall 50 mph. At this time my primary design tools are Excel and XFLR5, and of course my trusty HP42s calculator (yes, I still have one---can't beat the quality!).
