Hi,

I have toyed with this idea for a while. Try the following. Make elevons full span with a chord 20% of the full chord. Reflex the elevons to lie flat when the leading edge touches the table as a starting point. The aspect ratio (span/chord ratio) should be less than 6 and preferrably less than 5.

Elevator travel should be 10-12 degrees and aileron travel 10 degrees. Make sure that full aileron travel is possible both sides when the elevator is full up or down.

On a rectangular plan form with no sweep back the CG should be at 15% chord as a starting point.

Make a light hand launch glider at 1/2 scale, say, to explore CG, reflex and handling.

Good luck!

Sture
