Here is a thread with the official data on RV-14 W&B:
This page has some various data points:
My RV-14 is 1216 lbs at 80.29Ē when empty other than (very little) unusable fuel. Thatís 18 lbs lighter than N144VA and 1.04Ē forward. But N144VA is a painted airplane with an interior and the gear fairings installed, and I have not got around to those three things yet.
I primed most of the aluminum inside. I painted the interior. I built it to the plans except for Beringer main wheels and brakes, Flyboy Accessories tailwheel, and a half Raven oil separator mounted behind the engine on the left side. Single alternator, single E-mag, single Odyssey battery on the firewall, ELT in the tail. The panel is nice and heavy: dual G3X Touch, GTN 650, GTR 20, GMA 245R, GTX 45R, IBBS mounted to sub panel, and all the other accessories.
