Where is the CG at on the Extra? If the Edge is ~5", I assume the Extra is further back.
The 28% manual does not have the Extra CG specifications.
Yes it does on page 23 in boldface type. The Extra balances 2 1/2" to 3" behind the front corner of the wing tip. FYI the link still says Edge 540T manual, but it's been updated to reflect the Extras as well.
