Dear EF'ers
as I understand it you were supposed to have adapted the FE theory to match the fact that Foucault's pendulum changes its plane of rotation due to the Earth's rotation.
This change was supposed to involve the flat Earth rotating around its center (north pole) so that it would be able to create this effect. In this changed FE version the Sun is to remain stationary.
well... I did a search and noone seems to have said that this change DOES NOT FIX THE PROBLEM with FE theory.
See here a couple of simple drawings I made to illustrate my point withouth any math required to understand them:

If we have a round (spehrical) Earth Foucault's pendulum behaves exactly the same at the same distance from the equator (same lattitude) - points A and B. This means that at the same lattitude the pendulum rotates at the same speed - because the surface velocities at these lattitudes are of course the same for a round Earth. V1 = V2.

If we on the other hand had a flat Earth, the pendulum would have to spin FASTER at a lattitude below the equator (near the south "pole") since the surface velocitiy of a spinning flat Earth there would have to be faster. V2 > V1.
There is no way around this on a flat Earth. You cannot "solve" the problem of Foucault's pendulum by simply saying the flat Earth ROTATES... because the rotation of a flat surface such as the flat Earth does not produce the same effects (surface velocities) as does a RE rotation.
unless of course you say that difference slices of the Earth's surface move agaist each other so that if I move a couple of km to the north I'll see my southern friend drift to the east:D hehe. So AGAIN your FE would SPIN itself apart if you tried to match your FE theory to reality ... a reccuring theme in my examples I see

somewhat ironic also
