Inspection of the kit upon receipt last year found several items by prior builders best redone or modified. The vertical fin spar had a jagged lower edge where it had been trimmed, and needs work; best smoothed and dressed. Disconnected the rudder cables, removed the vertical fin, and used a small dremel wheel to dress the lower edge of the spar. Then reconnected all with final mounting hardware (not yet torqued). WAPITA.
