>>Presumably others have noticed that the first action of the movement of
the
anti-servotab is an elevator action.<<
As you noted, more marked with higher friction. The Banbi has the same anti
balance tab but uses variable spring bias to give pitch trim. The friction
is likely to be lower because it doesn't have the large bushes we do.
New builders note, make absolutely certain your elavator torque tube has
almost zero friction. This is achieved before the top goes on the fuselage
with judicious extra stiffening of the shell.
