Flying wing - Mod from GASB One

UPDATE FEB 2017: It flies!! I am very happy with the design. My custom nose is a little longer than the stock GASB One so I needed to push the CG a little bit (3-5mm) forward of the "bumps" on the bottom. My flying weight is about 525g. I am running a 2204-2300kv on 3S and 5X5 prop. https://www.amazon.com/gp/product/B01KJ717NW/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1 Re-Mix of this thing: http://www.thingiverse.com/thing:1659724 I made proper length elevons and stretched the nose. The CAD work is a little rough because I just wanted to get it close. Most folks complained about the lack of control surfaces and I didn't want to waste time building a poorly flying wing. Let me know what you think. https://www.youtube.com/watch?v=vhVB_Q2cBv0
