Winds from the south west. Abbreviated flight due to vibration on the port side cage. It was pretty dramatic, I looked back to check fuel and the outer cage rings and the tubing was vibrating like a concert grand bass string. I’m thinking it’s prop balance…. possibly more… the bad weld that was repaired with gorilla tape perhaps. I couldn’t spend any time with it today but will have to before the next flight. I did find the Lake Suzi Airstrip. It looks doable.
