Hi All,

I just got my Somethin Extra ARF and I'm enlarging the rudder and elevator by 1". I was planning on adding a 1" counter balance to both as well. Is that enough of a counter-balance to make a difference?

One more thing, I was told the counter balance will not only add surface area to the control surface, but also put less stress on the servo since it is on the other side of the hinge line (working with the servo to move the surface). My question is this, if I put a counter balance (on the rudder for this example) of 1", half the surface added above the original top of the rudder will be behind the hinge line. So, doesn't the benefit of what's in front of the hinge line get negated by what you have to add behind the hinge line? I'm not a aerodynamics whiz as you can see....it just doesn't make sense to me. Can anyone enlighten me on this.

Thanks,
Harold
