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

I made proper length elevons and stretched the nose.
