Thanks Herk. So you're thinking that due to the sweep, that the winglets would be more effective than the central fin??

The Fin is fixed, no rudder. I'll start with the central fin and see if I have any complaints. I'm planning on a wing loading from 9 to 15 oz/s.f. so it should really move least compared to the Manatee. I'm more concerned about pitch control than yaw.

Attached is my guess at the CG range.
