The "balance" or sections of control surface reaching forward over the fixed surface, add a lightening effect to a larger control surface. Meaning it makes it easier to deflect a larger control surface with the same effort applied. There is a balance [sic] to be struck in order to prevent flutter, however. I did do the math and compared to other designs in the same speed range. Flight tests will show my results.
Realistically hoping to fly it summer of '15. Full reports to follow.
Once it warms a little I can get back to working on it. I don't have much for "hard parts" work any more, some plumbing and FWF. Then wings and covering. It may fly this year, but that's not a realistic goal.
