A friend/neighbor is getting close to first flight with his RV-8. Doing the W&B and lining up a DAR.
The empty W&B came out to 1118lbs and 77.4". IO-360, Hartzell C/S prop, nothing crazy.
The DAR says that it's too far forward (Van's published range is 78.7"-86.82" inches aft of datum) and is saying that weight needs to be added to the tail to bring it into range before he'll sign off on it.
Isn't that the CG range is for a loaded, ready to fly airplane, not the empty? For example, by this thread here, many of the posters are forward of the CG limits according to this particular DAR and he wouldn't sign them off.
Even on the EAA's website, in the "Building Articles" section, the example aircraft (an RV-8 fortunately) is forward of the limit when empty. Scroll about 3/4 of the way down this page.
My neighbor is going to call into Van's on Monday for the official word.
