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? |
