There is interference while riveting the trailing edge / rear spar near the aileron hinge. I manage to fit a pop rivet in one of the holes but the other is just blocked. Looks like the reinforced rear spar addendum is the culprit. Without any advice, looks like one hole will just have to be filled at some point.
When I get near my ipad I can upload some pics of what im talking about.
