An aside....this evening the CG of the glider was checked following the flight testing and balancing done yesterday and I'll once again have to give kudos to the aeronautical calculator. It had projected a CG at 2.58" aft of LE at root and that is exactly where the CG produced the best glide endurance.

Also noted was subtle changes have large effects on a light airframe. Glide endurance went way up when following slight balance changes.
