Weight and Balance with new 670

[SlyRoo 14]

Hey Guys,

I just installed a 670 on my Avid MK IV HH. I am now doing a weight and balance. I just wanted to see what line do you use to level the plane. Do you use the bottom of the door? I have the Excel file and my old WB from builder. Also what do you use as the datum line, my paper work is showing the leading edge. Just want to confirm. Also any info on doing this process would be appreciated. thanks.

Leading edge of wing is the datum.  Manual shows leveling the rib just inboard of the right wing lift strut attachment.  If you don't have a manual, there is one posted in files and forms sections of this site.  JImChuk
