Bill Evans Shooter CG
I am just finishing a Bill Evans Shooter. It is one of his tailless designs from the Scimitar series. It's time to balance it. It has a slightly tapered wing. Using the CG as is is on the plan it's only 1 5/8" from the leading edge in a chord of 11 1/2" at the root and with the taper measuring out from the root at 90 degrees puts the CG exactly on the wing tip. Using the formula from April 2012 "Flying Models" written by Greg Moore and using 25% of the Mean Aerodynamic Chord puts the CG at 2 7/8" from the leading at the root. That's a difference of 1 1/4 " in a 11 1/2" chord. The second as according to the formula "looks" better. On the other hand Bill flew/ flies the heck out of his planes. Not sure what to trust? Looking for advice please.
