Completed a weight & balance on my tri-gear KR-2 today.  Started from 
scratch and re-measured the wheel locations.  The main wheels were 0.25 inch 
further forward and the nose was 0.5 inch further forward than from the 
numbers previously used.  One explanation would be a new nose wheel strut. 
For the mains it was probably closer attention to detail.  Instead of using 
one number for the fuel arm, I made progressive measurements adding five 
gallons at a time and derived an arm number each time.  It does change, 
granted, not by much.  I think that is due to the tilt of the tanks loading 
to the rear and then adding fuel forward as the tank fills.  Empty weight is 
781 pounds; FAA calculated gross is 1178 pounds for a useful load of 397 
pounds.
With my tender body onboard the CG ranges from 12.4" full fuel to 11.2" 
empty.  Just guessing from my first flight results, I could use the extra 
stability.  The price for that extra stability is adding 30 pounds of lead 
to the cowl about 0.5 inch behind the spinner.  Really need to move the 
engine forward another 1.25 inches for best efficiency, but that major 
operation will wait until next winter.  Right now the airplane and I are 
ready to fly.
