Al,
I tried the forward stick nudge today, the airplane just keeps going steeper
and I have to pull back to prevent overspeed in a matter of several seconds.
You probably have the floats to slow you more I am guessing. Seems to me a
certified airplane has to recover this manuver. I don't really know what
causes this. Maybe the counterbalance in the elevator?

Mike:
Presumably, you narrowed the spades to 4". I wonder if you also rounded
the
tips? Anyway, next time you're up, try flying along with no pitch input,
then nudge the stick forward, and let the airplane recover. How quickly
does it come back to the trimmed attitude? In my case, while it isn't
something you notice immediately, the answer is "a lot slower than any
production airplane I've ever flown - maybe 10 or 15 seconds". Now, I'm
on
amphibs, so there's a lot more inertia involved.
Personally, if I was doing it again, I'd remove the 4" from the inboard
edge
of the spades, and lengthen the stab to fill the gap, bit that is
structurally a bit more complicated. Better still, I'd keep the spades at
8", but shorten them by a third, and increase the mass balance, but I'd
like
to speak to somebody who understood the aerodynamics a bit better before
trying that. Anybody know such a person?
The other question I'm waiting for you to answer is "where is your
elevator
in level flight?" I'm contemplating another 1/16" under the rear stab
attach fitting at the next annual.
