There is a simple answer as to why PXT operated by Sydney Seaplanes in Turbo Charged.... Cessna do not produce normally aspirated 206's anymore! The aircraft is a 2006 model on the new model wipline floats. Almost a different machine compared to the old U models the new Lyc engine and prop combination make significantly more torque and the new floats perform much better.
Simple it is then. Well that wasn't as much fun as I was hoping it to be...
