We had our taildragger tip over as it turned through the wind bringing in a strong tailwind. A very gentle and totally unrecoverable process once it had started.
The group member in question said later that he tended to hold the stick back being used to the nosewheel approach of stick hard back to relieve weight on the nosewheel and didn't recognise the effect of a tailwind in a sharp turn.
£11.5k bill, though the insurers picked most of that up......
