So my next upload will apparently be this Unmanned Combat Air Vehicle developed by Boeing for the Air Force:

Yaw stability in the tailless design is not a problem, and it flies and handles pretty well already. The only problem I'm having with it is that the elevons (combining roll and pitch control) suffer from control flutter at speeds above 350 Knots indicated. So I figured instead of just thrashing through this problem as I've done many times in the past, I'll ask what other designers have discovered and done to avoid flutter.

I'm even running simple, preliminary bomb runs with it over Area 51:

I started this effort as a lead-in to producing the larger and more capable Boeing X-45N ... the Navy version which will be doing automated carrier approaches and arrested landings in about two years from now. Boeing is currently building the first N version, and they are developing the automated landing hardware/software using a modified F-18 Hornet.
Anybody discovered good solutions to cure control surface flutter? (my frame rates are above 85 FPS in X-Plane v8.40)
