Someone mentioned using the firewall to keep the numbers
positive. That only works on a taildragger. On a tri-gear, anything
forward of the firewall is negative. Select a datum, even beyond the
nose , spinner, whatever, of the aircraft and your numbers will
always be positive, whether it's
My wife just stated you are very correct. You just might become

I think I kind of misread the question too...the c.g. range is based on the
wing planform. The forward limit is can be manipulated with length and
size of the horizontal but the aft limit cannot. If your spar shifted in
relation to the leading edge, you should base it on the leading edge. That

If I remember correctly, the Diehl skin instructions don't call out a
change in CG location over the KR2 plans, even though the wing planform
changes a bit (just taper and length, I think).
g the centerline to 3 to 3.25" below
the longerons? I will still have about 9.5" ground clearance.

Not a problem as I would still have approx. 9.5" ground clearance.

I am in the process of determining the cg on my project. In comparing cg
location, RR plans show the 8" cg range with the fwd edge of the range starting
8" aft of the leading edge of the wing. Based on the profile of the 48" rib,
the leading edge of the cg range is 2" fwd of the front
