Haven't done any calculations, just TLAR'd it. It's 16.5 ft long, 15 ft wingspan with 90 sq ft wing area all aluminum and the vw engine would be bolted directly to the firewall for simplicties sake. The pilot sits about on the cg and the root chord is 10 ft so I'm hoping that would make it a little less prone to instability due to varying c.g.

Because I have no idea what airfoil to use (thinking maybe the same as the Dyke Delta if anyone knows what that is) I used a NACA 0018 at the root and a 0015 at the tip. I think I need reflex on the tailing edge but don't know how much. Anyway comments and suggestions welcome.
