Hi mixjsj

It look very hot... Like Claus says, build it... just because it has forward wing dose not make it unstable, I have designed a few FW that flue very nicely without any stabilizations. I would remove some of your anhedral.

Well is a mater of taste, but I would chance the transition line from the nose- to the start of the wing. Very impressive cad work by the way.

Yes, that is why tipstall problems is reduced with FSW.

mine isn't a v-tail but is otherwise very close to your design, and it flies perfect. I used washout at the tips, about 3/32". very stable flyer.

A little something, for the past 11 years I've been messsing with swept forward design, true swept forward. A V-tail SFW has a tendency to snap out or switch ends in a heart beat. Your design with the ventral fins may do better.
Nice Cad work too! need more?

Claus helped me getting started with this one, it the same as sloperjoe made.... Still needs a bit of drawing.
