I don't actually know what I'm talking about, but what you're looking for IMHO,
is a constant sideways force independent of sideways movement of the stick; so
the bungee should be long enough to make the force approximately constant. To
avoid the situation of a completely loose bungee when no sideways force is
needed
a constant tension bungee pulling gently the other way could be used.

not increase non-linearly as the stretch? If this is so, does the stick force
not become unbalanced when moving off center/neutral? Even if the bungee force
is linear as it stretches, if one has it set for no pull on the stick with the
stick neutral (case=no trim required), the stick would require more pull in
the direction of stretching the bungee vs the other...no? Are the bungee forces
so small that one does not notice these effects?
