From the photo it is a Delta, with the Wingtips look like they are going to a High Aspect Ratio Section, almost Blended Wing Body-ish. No center Cuspidate ( aka “Bat-Tail” ) Tail like the B-2 or the Horten 229. Which leads to the question why not the center stub tail which the R/C modeling community has found out really works...
No vertical stabilizer is required and it only adds drag.
Once you accept that you are reliant on a working computer to fly, you can get rid of the tail and control yaw with tiny movements of speed brakes at the wing tips.
