This thread has gone to a he said/he said debate. The last post claims that the poster did not fly after one and a half months of purchase of the RV9A(inspection was on Apr 27,2017) However on FlightAware there is a flight on Dec 10, 2017.
Also this link shows 18 flights after April 27.2017
One other question. Why didn't the purchaser contact Vic immediately if there were problems with the aircraft.
