Clearing JUST enough skin and foam on the spar to clear the K-1000 nutplates, I used 5 min flox to bond the mounting plate for the roll servo. Also floxing in the holes in the spar leaving no gaps. I then added an EZ poxy flox edge around the plate and added 2 plies BID and peel ply. Super easy job thanks to the Fein tool. There is No excuse for not having an autopilot installed. fun ez job.
