My Bd-4 is headed to the airport for weighing soon. If the empty weight CG is roughly 25% MAC, what is a reasonable place to put the fwd and aft limits in terms of MAC? Would the original limits determined by Jim Bede still apply even though mine is substantially heavier on the nose and the fuselage aft of the main gear is stretched? I'm wondering where the original numbers came from, I figure there are knowledgeable folks on here who can help with this! Thanks in advance.
