Kfm4 Flying Wing Maiden Flight

I think the basic planform is fine, it's just the finer details that need to be tweaked. The thrust angle is probably the main thing, I'm going to remove it totally before I fly it again. The elevons also have very little command of the airframe, and I'm not sure if it's because the wing is flying slowly and thus the control surfaces do not provide much force, or its because I need much more throw.

The other thing I'm going to modify before the next flight is the battery - I'd velcro'd it onto the wing, but it came off in one off the flights. I'm going to embed the battery into the airframe like my Teksumo to be held down with a velcro loop, that will keep things tidier, and probably less drag too!
