Flying wing with differential split-rudders

Requires FAR

I finally managed to make a flying wing that has yaw control just by differential break rudders. Just stock parts, no reaction wheels, no thrust vectoring, no other mods. Others have probably done this, but I still think this is kinda cool 

How does it work?

The wings are canted upwards into a slight V form. On each wing there are 4 pairs of split elevons - that is two elevons stacked on top of each-other. The elevons are set to +/-100% yaw (-100 top/+100 bottom) with full ctrl deflection and ~30% roll. I tried using a M-form for the wings but that didn’t look as nice, although I did experience less roll-pitch coupling.

How do you fly it?

Carefully. Immediately after take-off set SAS to prograde and never ever turn it off. Minimum take-off speed is around 60m/s. For landing use airbrakes and reverse thrust and touch down at less than 80m/s. The plane suffers from some buffeting due to the SAS, but you can manually counter that. It does have some inertia coupling so it’s best to roll, wait, and then pitch. Other than that this is actually flyable and stable even at transonic speed (tested up to mach 1.05). No warranty!
