Thanks Alex. There's a lot of guys building nice foamies but not too many posting build threads or pics these days. I wish they would because I'm still learning.
If you look at this pic from the 3rd post you can see 2 tiny holes on the bottom where the old servo locations were. That's where I added lead shot. I think it was 4-5 oz in each along with some epoxy. On my 70oz I added 10oz to each and came out nose heavy despite making some heavy winglets.
