airfoil sweep
I didn't mean to imply there is anything wrong with the templates. I
really appreciate the templates. ..I am using the as 5048 templates
myself. I was just answering the question about what they do to the cg
range and how easily that range can be changed. My spar caps are thick
enough that I

These airfoil templates were drawn up at a time
I understand the reason...it is a great thing to have the laminar flow
airfoil. Unfortunately the reduction in sweep changes the location of the
mac. I did the calculations a few months ago...and I can't decipher my

Duh...504x, not 405x! At least I got RAF48 right.

The sweep is different because the airfoil shapes (AS405x and RAF48) are
different with regards to thickness vs coordinates, so to make the
airfoil
