Are you saying that the Galloping Ghost, or Strega, couldn't be rigged
for minimum drag at 500 mph because they'd then have to land at 200?

Minimum drag, sure.

Zero drag, no.

You're the only one who specified Zero, wasn't me.


Note that I never said the Stabilizer produces no nose-down force at 500
mph. I'm only doubting that the Trim Tab/Elevator are doing much work
there, at all. Set the Stabilizer to do the work, and lift (downward)
comes by way of Angle of Attack. But set the Trim Tab and Elevator to do
the work, and lift (downward) comes by way of Camber. And not even a
good camber, it's all zig-zagged and creased.

It's still drag.

Well then, why ever point the nose up to climb? Just lower the flaps and
add power, it's only drag.

And you can calculate how much will be there under any given conditions.

Really?
