Thanks Gary, I saw your post about this earlier. Last night I was working on cutting my cowl and I noticed that one of the blind nuts on the bottom of my cowl mounting blocks was really messed up...stripped a few M3 bolts trying to clean it out, finally said "nuts" to that and decided to replace the blind nut. Yeah for trimcraftaviationrc.com where I had recently restocked my hardware bins to include all sorts of M3, M4, and M5 bolts, nuts, and blind nuts!
Anyway, it was very easy to remove the blind nut...I was able to pry it out with a screwdriver...the glue used to attach the mounting block and the blind nut was kind of sticky and definitely not epoxy. I replaced the blind nut with a new one and now the M3 bolt goes in just fine. I will reglue the mounting blocks with epoxy this weekend.
Again, thanks for the heads up on this one...that's what build logs are all about!
