Thanks, Ryan and Wingwiz. 6-1/4" is the aft rec. and 3/4" behind the rear edge of the spar. So, 7" is 3/4" aft of that. I usually have my CG aft (where it's supposed to be) of mfr's and most people. I like it to be hands off inverted. Sounds like it will fly at 7" but that's about 1.5" behind the spar. Anyone else?
