By the way, if one were calculating CG for a canard plane, I believe entering the LE / LE distance as a negative number produces the correct results. Do you concur?

Oh, never mind the silly question. I just found a Canard CG calculator at [link=http://adamone.rchomepage.com/cg_canard.htm]http://adamone.rchomepage.com/cg_canard.htm[/link]
