It will in a flyable range at 10-15% MAC.

Add 2 "cool looking" wingtip fins and possibly a central fin if you like and program the elevons so that there is more "elevator" movement and not very much "aileron" movement. Have dual rates set up to give yourself an emergency option if you guess wrong on the set up....but there is no need for dual rates once you get the elevon movement and the CG figured out to your liking.

Flying wings do not need reflexed airfoils. I have built and flown several wings in the .049 to .50 size range and they only need the slightest amount of up trim to fly level. The faster they go and the lighter they are, the less up trim is needed.
Set the elevons dead neutral and let the airplane tell you how much "reflex" is needed while you trim it out.
