SUBJECT: Drilling for the revised tailspring in the stern.
Emmet:
Thank you for the kind words. Yes, 1inch up from the OUTSIDE
seems to direct the tailspring correctly. What put me onto it was that
unless you have the correct number of plywood layers, the supplied bolt will
not suffice. Also, photos of completed aircraft show the tailspring exitting
through the bottom layers of the stern. That can only be accomplished if the
number of plies is close to ideal. If a longer bolt is required, one should
check with the designer for the proper bolt. Bolts have a penchant for
stretching when not properly specified ot torqued.
Happy landings
