Pimmnz, you're right of course. Sorry if I made it sound differently. I passed by the CG issue.

The CG location ahead of the neutral point sets the stability margin. BUT.... the wing to stab angle isthenselected so the model trims to level flight at the desired airspeed for that CG location if one wants to avoid a healthy case of upelevatortrim angleto stabilize to level flightat the trimmed airspeed.

This last bit is the part I left out. I sort of assumed that folks would fill it in. Does that make it more complete?
