Yaw Stability

[SkySteve]

War Eagle,
These mods were made to my model I a few years back. I made the mods to the tail feathers to change the yaw issues. The mods corrected it and made the plane a joy to fly. I was just throwing the photo out there to show that the yaw factor of the early models can be addressed. But you are right, at the time, I did make several major modifications.

As you can see from Steve's photo it is an extensive modification but certainly doable. Steve did an outstanding job and I can testify first hand that it flies as good as it looks.

There is a Kitfoxer here in Dallas that did the same mod.

I'm doing both my horizontal and vertical tail:

Looks great Larry. Love the shape and counter balanced controls.

Larry,
Looks really nice! I've wondered, what different effect does the rudder have with the top over the vertical stabilizer? Same question regarding the horizontal stabilizer and elevator?

[Av8r3400]

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.
