Dbot,

I did one in blue foam years ago; the version with vertical fins. It lacked fin area and performed some spectacular wing-overs. I was foolish in not using a reflex flying wing section.  The tailplane ran out of up elevator to trim. The wingtips may cause the tailplane to be subject to strong up-wash and a really nose down angle is needed on the tails to trim.

But, don't let me put you off. But I would make a chuck glider to test the concept before making a nice model.

I must try and find a picture.

Yes, won 2009 FAC NATS (outdoor FF) and has always maxed its three flights. It is a very stable flier but requires clear vertical stabs for directional stablility. Electrics are Atomic Workshop.

What sweet models. In my studies of flying wings,I think a inverted airfoil on the wing lets would give the needed elevator control.

If you look closely you will notice the BV208 (right) and BV215 (left) have similar wings. You find this wing in Steve Bage's plans on this site.
The the center BV212 s have a different wing. The wing on the BV212s is very similar to that on Richard Crossley's Me163 kitted by AeroGraphics. I obtained Richards layout drawings but modified the airfoils to be flat topped, reducing the impact of the reflex. Both wings trim out with tip plates but the Crossley airfoil requires noticeably less up evelon.
My BV208 was designed for the smallish Atomic Workshop Voodoo 25. My next model will be somewhere in the area of 27 " wingspan so I can model details this very unique aircraft deserves.
I was never thrilled with the camo schemes of these models. All  4 competed in FAC so they matched schemes dreamed up by some poor graphics art work.
I like the side view you display.
