That's good, but I've heard of one case where the ailerons
moved together up and down, not differentially. Direct lift
control, but is right up or down? I don't that airplane
actual tried to take-off.

If you box the control you can check for full and
unrestricted travel for elevator and ailerons as well as
correct rigging. I have seen wire bundles get loose and
block control travel and you might see the ailerons move
correctly, but you might not have full travel of the
elevator.

This is a killer, take off with engine failure, you can have
a good chance to land without any damage. Have the controls
locked, blocked or reversed and you're a passenger in a
missile. The WSU football team DC3 tried to take-off with
the gust locks installed on the tail, a C310 in Tulsa back
in the early 70s took off with the controls reversed and
immediately rolled into a smoking fireball. These are pilot
error. The mechanic made a mistake, but the pilot has to
check and verify... FREE and CORRECT. Test flying is any
first flight after any work is done to the airplane, from a
tire or oil change to a control replacement.
