I am going to modify a Kyosho Cap 232 Arf with a pull-pull system on the rudder. My question is that, after thinking the process through(I have learned my lesson about being hasty), I thought about this...

In a pull-pull system, when the surface is in the neutral(center) position, unless the pull-pull is absolutely perfect, the surface would have slight slack in each wire, and therefore the surface would be prone to flapping slightly back and forth(flutter).

Is this a problem? I havn't even set up the pull-pull, I was just thinking it through, and thought about this potential problem.

Thanks,
Philip
