That's an intriguing design Jason, thanks for the pictures. I'm curious about the reasons for using a delta wing on a pattern model.

I'm sure with some more testing it's possible to optimize the fences dimensions and remove the small roll coupling. The model had a little roll coupling before, but it was so small that i didn't even bother to mix it out. The fences just made it more noticeable. Anyway, i'll gladly trade a few percents of mix for the much improved KE performance.
