Looking for info as to where I come out on the normal distribution curve as per my weight and CG for my RV-14A. I came out with an unpainted weight and CG of 1236 Lbs and 77.5 inches. I have (14A) nose gear and Garmin panel and otherwise built to spec. Anyone care to weigh in or have resources to find if I am in the ballpark for empty wight and empty weight CG?

As you'll see from reading the thread mentioned (plus this one: http://www.vansairforce.com/community/showthread.php?t=133335) you're near the low end of the spectrum in weight and very forward on CG - particularly for an A model. Did you make a concerted effort to build light? I'm assuming you have limited options and no priming? Did you include oil, fairings, etc?

And here is a thread originally started to point builders to W&B info and examples on the Van's web site.

The links were broken for a while after the web site was upgraded but I fixed them a few days ago.

I agree that it looks like your empty C.G. is quite a bit fwd of what I would expect.
Could be for a number of reasons.
A slight leveling error while on the scales can induce quite a bit of error, or something rather heavy out front.
You don't by chance have an all metal 3 blade prop installed do you?
