Hi Duncan,
Gyro HL probably did a low pass at 1430/1500(ish) then but then headed off to Strathallan direction cause the grass was long.
Myself (G-RS) and 2 mates (another flex and a 3 axis) came in at just after HL would have been there. We went to the cafe and phoned HL who then came back and landed at about 16.15. We all left at about 16.30 (I was last to go due to taking pics of the others taking off) and HL hovered around till I was off the ground. Myself and HL landed back at Perth about 5 mins after Pete on the tower put his feet up for the day
