Drag rudders are very useful for yaw stabilization on flying wings. Especially for anyone who is trying to design a flying wing with no vertical fins. I decided to design controller that's totally dedicated to controlling drag rudders. The following video shows the drag rudders in operation.

I was just using some cheap spoilers just for demonstration purposes. The attached picture shows a drag rudder mechanism that I might use which is a scaled down drag rudders used on the Horten 229 Batwing .The following video shows a simple mechanism that I might also use.

Using spoilers, as you have there, will cause a reduction in lift resulting in a coupled rolling moment as well a decrease in efficiency. Use of split ailerons or a Prandtl-D configuration would likely be more suitable.
The Arduino controller makes it easy to connect my Eagle tree guardian yaw stabilization module . Besides, it was a a very interesting and challenging code writing project .
Just out of curiosity why did you see the need to add an arduino to the mix ? All of this can be done via mixing on the DX7 or any other modern controller.
