Hi Bob,
I kinda figured it has a large CG envelope. I saw here on the Universe there was a CG change that has not been corrected in the manual. I sent PCM an email questioning that and they verified the new CG location to be 10 5/8". With the new location I was able to remove a significant amount of weight needed to balance at the old location. So, like you said earlier, the fuel burn is probably not as big a factor as I was guarding against but I'm just trying to cover all bases, if ya know what I mean. Sounds like yours is really high-tech! I guess that really speaks volumes for the airframe.
