Slack Rudder Cables

When I adjusted the rudder cable tension the wings weren't on the plane yet and the nose gear was near the bottom of it's travel.  I had 25 pounds, both right and left.  But after the wings were on, the nose of the plane was several inches lower.  Since the firewall slants back this has the effect of loosening the rudder cables.  They are totally slack now!

Here's my question.  If I tension cables now the tension my be right on the ground, but the tension will increase drastically…

Value of Plans Built Zodiac

I'm looking into selecting an airport to keep my plane at once I've finished building it.  My question is, how much will it be worth?  The reason for the question is that one consideration I'm using for selecting an airport is the personal property tax rate.  These vary wildly from county to county here in Virginia.
