20 years ago a former mechanic posted (on the BBS network) that, of
the B-17 and B-24, one was all electric and one was all hydraulic.
Apparently the 17 was the electric one, but did that extend to the
control surfaces I wonder?

This says no.

I've poked around that aircraft as far as they let me, and seen the
inside of an engine but not the wing. In the preflight checklist
training film (just watched it again) the control check precedes
engine start. They move the controls to the limit and look out the
cockpit window to confirm the ailerons, elevators and rudder moved in
the proper direction, without first flipping any switches.
