mashp39, BTY, I neglected to mention that sometimes the C/G stated in the instructions are just flat out wrong! It seem like that happens more with ARFs than stick built kits but be aware that what is printed in your instructions MIGHT not be correct. Now that you know how to figure the C/G you can (and should) double check the position called out by the manufacturer. I don't know if it is a problem with language translation or what, but it happens. Be aware.
