Finished trimming the reverse side layup on F28. Cleaned the edges with files. It weighed in at .6125 lbs. This is about 12% lighter than the average posted on Marc's web page. After some checking I did find that another builder had similar results using MGS. I am going to keep building while researching and set up a visit from an EAA advisor for Bulkhead completion prior to doing the sides so that I can get a report early.
