If you know the location of the mains relative to the leading edge of the of
the wing you can make this determination. Let's say the mains are 8" behind
the leading edge, then they are at the forward limit for the cg envelope. When
empty and with the tail raised to flight position and the tail weighing nothing
then your empty weight cg is at the forward limit. When you add weight such as
pilot/passenger the cg moves back. Fuel, if it's a header tank will move the cg
back forward so you may be pretty close.

On Ken Rand's original KR-2 He had minus 1/2 pound when the tail was up in
the flying position. So your plane should be good.

attitude, I have almost no weight on the tail. Is this an indication that
it is nose heavy? Should I move the battery to behind the seats before I
bother with weighing?
